Quartz is one of the oxides of silicon, its chemical composition is SiO2, three crystal system. A translucent or opaque crystal; a colorless, transparent crystal containing impurities.
White said the milky quartz light red, called Rose Quartz, called Purple Amethyst, smoky quartz, Citrine Tan said, black is called smoky quartz.
Pure quartz can make a certain wavelength range of ultraviolet, visible light and infrared light through, optically active, piezoelectric and electrostrictive properties.
The complete production in the rock crystal quartz geode, massive ore veins produced in the heat, granular is an important part of granite, gneiss and sandstone and other rocks.
The number more than and 2 is the continental crust of quartz ore, after feldspar, hard texture, is the main component of granite.
Equiaxed crystal and columnar, double cone shaped six party collection type massive, granular, stalactitic,
Hardness Mohs hardness of 7.5
Characteristics of quartz:
1 brittle
2 with thermoelectric properties
3 refractive index of 1.533 ~ 1.541, birefringence difference of 0.009 dispersion of 0.013
4 quartz piezoelectric Piezoelectric property strong method produces a spark that is flint stone will be hard hit that friction.
5 common quartz inclusions are mainly crystal Hair crystal rutile crystal is mainly grass into the tourmaline crystal with water in quartz liquid inclusions of quartz containing green light blue rutile needle milky quartz caused by fine water hole shaped by turbid green quartz plate or fragmented chlorite composition may sometimes be green needle the internal Aventurine quartzite containing Aventurine actinolite green or reddish brown mica flakes or quartz Aventurine commonly known as yao. Common smoky black to dark brown smoke crystals are mainly related to these rocks contain a lot of radioactive uranium, thorium.
Advantage
1, scraping do not spend
The quartz content is as high as 94% quartz crystal is in the nature of natural mineral hardness only to diamond surface hardness can be up to 7.5 Mohs hardness is far greater than the knife blade used in the kitchen and other weapons will not be scratched.
2, no pollution
Quartz stone is made of composite material under vacuum conditions, be the same outside and inside dense without holes on the surface of quartz kitchen has excellent acid and alkali corrosion resistance of daily liquid substances will not penetrate the long time on the surface of the liquid with water or clean and bright and clean with a rag to wipe agent can be used when necessary the blade to scrape the surface of the retention.
3, with not old
The bright surface of the quartz stone is the result of not more than 30 complex polishing treatment of knife blade scratch not for liquid substance penetration will not produce yellowing and discoloration of the daily clean with clear water is simple. Even after a long time of use of the surface is as bright as new mesa without maintenance and maintenance.
4, burn not
Natural quartz crystal is a typical refractory material with high melting point of 1300 degrees above 94% natural quartz quartz stone completely made of flame retardant not caused by exposure to hightemperature combustion also have the man-made stone mesa incomparable characteristic of high temperature resistance.
5, non-toxic and no radiation
The surface of quartz stone is smooth and smooth without scratches and the structure of dense and nonporous material makes bacteria nowhere to hide and can be directly contacted with food.
The content of high quality quartz by the natural quartz crystal minerals of SiO2 more than 99.9% and to purify quartz crystal any may lead to heavy metal impurity radiation 94% does not contain raw materials in the body and other resin additive made of quartz stone there is no risk of contamination in the manufacturing process.
