The origin of quartz stone
Time:202017-03-02 18:01:15 Views:156
Quartz stone, usually we say that the quartz stone is a more than 90% of the quartz crystal with resin and other trace elements synthetic a new type of stone. It is through a special machine in a certain physical and chemical conditions to suppress the large size of the plate, its main material is quartz.
Chinese name quartz stone building materials main components quartz, resin, curing agent use cabinets, table top high hardness, corrosion resistance, easy to clean, no radiation
Quartz is a kind of mineral that is easy to become liquid when heated or pressed. Is also quite common rock mineral, in the three major types of rocks are there. Because it is the largest in the igneous rock, so usually the lack of complete crystal face, mostly filled in the other first crystallization of rock-forming minerals in the middle. The composition of quartz is the simplest silica [ie, silica. Silicon: silicon old name] (sio2), glass luster, no cleavage surface, but with shell-like fracture. Microcrystalline quartz is called chalcedony, agate or jasper. Pure quartz is colorless, but often contains different elements of transitional elements with different colors. Quartz is very stable, not easy to weather or change for his kind of minerals. According to the degree of crystallization of SiO2 can be divided into crystalline crystalline single crystal quartz, polycrystalline quartzite jade.
Formation process
During the process of intrusion of the magma, due to the change of temperature and pressure conditions, the hydrothermal-rich, bedding and fractured layers are separated into the metamorphic rocks of the surrounding rock, or the contact crushing zone along the magmatic rock Invasion, the formation of vein quartzite ore body. [1]
Quartz types: powder quartz, green quartz, white quartz, yellow quartz.
Quartz stone raw materials by categories: ordinary quartz sand, refined quartz sand, high purity quartz sand, fused silica sand, silicon powder.
Physical properties
Gloss: Glass Gloss Color: none, white, with a little gray, yellow to orange, purple, deep purple, pink, gray brown, brown, black

Streaks: white
Specific gravity: 2.65 ~ 2.66
Category: metamorphic rocks, metamorphosed from sandstone.
(1) brittle
(2) has thermoelectricity
(3) a refractive index of 1.533 to 1.541, a birefringence difference of 0.009, and a dispersion of 0.013
(4) quartz has a strong piezoelectric (Piezoelectric property), that is, when the friction hit the friction will produce sparks, which is the flint fire method.
(5) Quartz common inclusions are: hair crystal (Hair crystal) - mainly rutile. Grass into the crystal - mainly tourmaline; water gallstone crystal - quartz in the liquid inclusions; blue quartz - containing light blue rutile needle; milk quartz - caused by the water holes cloudy; green quartz - from the plate Or debris-like chlorite composition, and sometimes may be green needle-like actinolite; sand stone (Aventurine) - quartz rock contains green or reddish-brown mica slices, also known as Yao Shiying, commonly known as Dongling stone. Common smoke black to dark brown smoke crystal, mainly these rocks contain a large amount of radioactive uranium, thorium elements of the relationship.
1, scraping does not spend
Quartz is the quartz content of up to 94%, quartz crystal is the natural hardness of diamond after the natural minerals, the surface hardness can be up to Mohs hardness of 7.5, much larger than the kitchen used in the blade and other tools, hurt.
2, do not pollute
Quartz stone is made under vacuum conditions in the case of a dense, non-porous composite material, the quartz surface of the kitchen acid and alkali, etc. have excellent corrosion resistance, the daily use of liquid substances will not penetrate its internal, long time The surface of the liquid only with water or clean and bright cleaning agent can be wiped with a rag, if necessary, the blade can be used to scrap the surface of the retractors.
3, with the old
Quartz stone glossy bright surface is after more than 30 complex polishing process, will not be blade shovel scratches, will not penetrate the liquid material, will not produce yellowing and discoloration and other issues, daily cleaning only rinse with water You can easily. Even after a long period of use, the surface is also the same as the new table with the bright, no maintenance and maintenance.
4, can not burn
Natural quartz crystal is a typical refractory material, the melting point of up to 1300 degrees above, 94% made of natural quartz quartz flame completely flame retardant, will not be due to contact with high temperature caused by burning, but also with artificial stone and other countertops can not match the high temperature characteristic.
5, non-toxic without radiation
Quartz stone surface smooth, flat and no scratches stay, dense non-porous material structure makes the bacteria nowhere to hide, can be in direct contact with food, safe non-toxic.
High-quality quartz stone with a selection of natural quartz crystal mineral, the SiO2 content of more than 99.9% or more, and in the manufacturing process to purify, the raw materials do not contain any possible lead to radiation of heavy metal impurities, 94% of the quartz crystal and other Of the resin additive makes the quartz stone without the risk of radiation contamination.
Variety identification
1. Monocrystalline SiO2 gemstone transparent, crystal shape of the SiO2 single crystal (including double crystal), mineral name for the single crystal quartz, that is, the broad sense of crystal, narrow crystal refers to the colorless and transparent varieties.
2. (1) the basic nature of crystal Crystal is a three-crystal system, the common crystal shape for the column, the main simple shape for the hexagonal column, rhombohedral, columnar crystals often developed stripes and polygonal erosion, crystal Sexual, with a unique bovine eye interference map, refractive index 1.544-1.553, birefringence 0.009, very stable, no cleavage, shell-like fracture, fracture can be with grease luster, Mohs hardness 7, density 2.65g / cm. Crystal is usually colorless and transparent, but with impurities can appear in a variety of colors, according to the color can be divided into amethyst crystal, citrine, smoke crystal and other varieties.
3. (2) crystal varieties and identification of crystal: colorless transparent pure silica crystal, which can contain rich inclusions, common negative crystal, fluid inclusions, solid inclusions. Negative crystal is an important basis for determining natural crystal. Solid wrapped body wrapped in rutile, tourmaline, actinine was fine needle-like orientation arranged in the quartz crystal, like hair, used to this crystal called crystal, and some other solid inclusions in the crystal can be The formation of a beautiful picture, as people love the ornamental stone.
Amethyst: a purple crystal, is caused by trace iron in SiO2, the irradiated, trivalent iron ions in the electronic shell of one of the pair of electrons are excited, the hole in the visible light at 550nm production , So that the crystal produces purple, but unstable, heat easily become trivalent iron, so amethyst easy to fade, amethyst color distribution is often uneven, was lumps, sometimes see parallel ribbons. With a weak to moderate dichroism, may appear in the crystal of all inclusions, but also have the characteristics of the "zebra" and spherical, droplet opaque dark inclusions.
Smoke: a smoke to brown and black crystal, the composition contains a trace of aluminum, and the crystal produce smoke. Smoke crystal can become a colorless crystal after heating.
Yellow crystal: a yellow crystal, composed of trace iron from the composition. Huang Jing generally more transparent, the internal characteristics of the same with the amethyst, the market is mostly amethyst crystal treatment.
Green crystal: a green crystal, the natural output of the little, mainly amethyst heating; or crystal containing green minerals (such as chlorite) inclusions and color.
Furong stone: also known as rose quartz, light to the pink crystal, the color is shallow, due to the composition of trace amounts of Mn and Ti and color, single crystal less, usually compact block aggregates, was cloudy milky appearance , Sometimes with directional arrangement of needle-like rutile inclusions, and thus ground into a gem can display stars.
Two-color crystal: a purple and yellow coexistence of the crystal, purple, yellow, respectively, occupy a part of the crystal block, the two colors of the transfer film has a clear boundary, the color is due to crystal within the double crystal, purple and yellow were developed The r and z faces in the double crystal monomer. Quartz cat's eye: When the crystal contains a large number of parallel arrangement of fibrous inclusions, the arc-shaped gem surface can show cat's eye effect, the general quartz cat's eye surface is higher, fibrous inclusions clearly visible.
Star crystal: When the crystal contains more than two sets of directional alignment of the needle-like, fibrous inclusions, the arc-shaped gem surface can display the star effect, usually six stars, can also have starlight.
1. Polycrystalline SiO2 matrix composition of minerals mainly fine quartz stone, can contain a small amount of mica minerals and hematite, goethite and so on. Amplification check when the quartz is a typical granular structure, the particle size is generally 0.01-0.6mm. Aggregates were massive, micro-transparent to translucent, density and single crystal quartz similar to 2.64-2.71g / cm between the point of the refractive index of 1.54 or so, pure colorless, often due to small Colored mineral inclusions and color. Common varieties are:
Dongling stone: for a quartzite with a stone effect, the market is common for the chromium mica of the green Dongling stone, microscopic micro-transparent, mainly produced in India. The quartz particles are relatively coarse, 0.1-0.6 mm, and the flaky minerals contained therein are relatively large and are oriented in a substantially regular orientation. Charles filter slightly brownish red.
Dense jade: due to the production in Henan Province, named after the county, is a 3 ~ 5% fine scaly sericite dense quartzite, green series, with light green, green, green beans and so on. Dense jade and Dongling stone compared to more delicate, dense, the size of its quartz particles to 0.02 ~ 0.25mm-based, there is no obvious sand stone effect. Magnification check at a higher multiple can be seen under the small green mica more evenly distributed mesh. Gui Tsui: named for producing in Guizhou Province, is a green kaolinite with fine quartzite, was uneven with gray hue of the green, generally only used for low-end jewelry.
Beijing white jade: named for the original suburbs in Beijing, is a delicate texture, glossy oil white quartzite, sometimes used to impersonate suet white jade, with its lower density and refractive index to distinguish.
"Malaysian jade": is a more structured green colored quartzite, often used to pretend to emerald. Under the conditions of amplification of the typical grain structure and relatively low refractive index and jade distinction, GB (GB? / T16553-1996) has been prescribed without the name, and with quartzite (treatment).
1. Submerged SiO2 enamel lattice aggregates, in the orthorhombic polarization performance of the whole bright, dense structure, can also be spherical, radial or microfiber-like aggregates, the density is relatively low quartz, the measured refractive index 1.53, the density of 6.5 ~ ~ .0g? / Cm mainly chalcedony, agate, jasper, Australia jade four varieties.
Chalcedony: ultra-microscopic aphanitic quartz aggregate, single crystal was fibrous, intergranular microporous filled with water and bubbles, the density is lower than quartz, about 2.60g / cm. As chalcedony porous, so easy to dye, the market common color bright chalcedony are stained. It is worth mentioning that the color of the chalcedony after dyeing more stable, itself is a low-grade jade, the national standard for the optimization, no need to explain.
Agate: chalcedony with a band-like structure, sometimes surrounded by empty holes, sometimes filled with crystal quality, agate is the most common natural color white and gray, but also yellow brown, brown, blue, lavender Wait. The basic properties of agate with chalcedony, according to the body characteristics, the color distribution of the following special varieties.
Moss agate: is a uniform, translucent containing dendritic green chlorite or black manganese oxide, red iron oxide chalcedony. Encapsulated impurities are often moss-like, generally used as ornamental stone, also known as the scenery agate, agate is a valuable species.
Onyx: also known as strip agate, is a relatively simple color, strip is relatively straight agate. Usually used for stone and relief, the common agate can have black and white strip, or red and white strip, when the onyx strip fine to the same as silk, known as wrapped wire agate.
Watergrass agate: is a kind of liquid-containing inclusions that are visible to the naked eye and rotates the agate vapor-liquid inclusions.
Jasper: for a more impurity with chalcedony, the most important impurities for the iron oxide, so the jasper is often red, but also because of other impurities and was green, dark blue or black. Jasper opaque, shiny dim, a different color of the strip, color block each other, like a beautiful natural scenery of the jasper called landscape jasper; a dark green with its red dot jasper blood drop stone.
Australia jade: is a green chalcedony, due to trace nickel and was green, color more uniform, transparent to translucent, mainly produced in Australia.
1. SiO2 account of jade This is a due to the role of SiO2, but retained the shape of the original material made of quartz jade, an important variety of wood and silicified wood.
Wood change stone: is SiO2 part or all of the account of amphibole asbestos, while retaining the product of fibrous asbestos, due to texture and color, such as wood grain named. Wood variable stone opaque, hardness 6.5 ~ 7.0, density 2.?64 ~ ~ 2.71g / cm, refractive index 1.54 ~ 1.55 (points). Color is brown, brown, blue, blue, blue is the residual blue shale stone asbestos color, and brown, brown is the iron oxide - limonite caused by the color can be Wood stone is divided into tiger eyes stone, eagle eye stone and other varieties.
Tiger eyes stone is yellow, yellow wood change stone, the finished product can be silk silk luster, when the composition of the tiger's eye stone finer, arranged neatly, the arc-shaped gem surface can appear cat's eye effect.
Eagle Eye stone for the blue, gray and blue-based wood stone, SiO2 account is not sufficient, the residual amphibole asbestos more.
Silicified wood: when the silica of millions of years ago buried in the underground trunk, and retain the shape of the trunk and its fibrous structure of the product called silicified wood, chemical composition mainly SiO2, often containing Fe, Ca and other impurities, color For the yellow, yellow, yellow, etc., opaque. Hardness 6.5 ~ 7.0, density 2.65 ~ 2.91g / cm, point measurement refractive index 1.53. To bright colors, strong luster, wood structure clear, dense texture as well.
The main purpose
Quartz stone is the main material of quartz, rich color combination to make it a natural stone texture and beautiful surface gloss. (Series of hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc.) and home furnishings (kitchen countertops, shopping malls, exhibitions, laboratories, etc.) and home decoration (kitchen table, Washbasin, kitchen and bathroom wall, table, coffee table, windowsill, door sets, etc.) field, is a non-radioactive pollution, reusable environmental protection, green new building interior decoration materials. It should be noted that the quality of quartz stone is good or bad with the amount of resin has a direct relationship. Quartz stone in the higher content of quartz, the lower the amount of resin, the better the quality, the closer to the natural, the more difficult to deformation. Experts pointed out that when the quartz stone resin content of more than 10%, the corresponding technical indicators will decline, when the quartz stone can not be called the real quartz stone
