Silicon Dioxide is a compound of silicon and oxygen, much seen of the mineral Quartz. It is utilized in many forms. Because silicon is a semiconductor. It is used to make smaller circuits, used in electrical equipment, such as computer, radio, television, and making solar cells. The silica-based glass is a component of the quartz watch in silicon carbide (SiC), using cutters, grinders, milling machines in the form of silica gel, using a look-up, used as an adsorbent in separation by chromatography graphene as silicate, used to make pottery, glass fibers, optical fibers in the silicon, which is a polymer of silicon. Silicon is a substance that combines with water, non-conductive, heat-resistant, and swift reaction, the electrical insulation, and a coating material to prevent chemical reactions.
Benefit
Silicon and Alloy
Applying the purest silicon was mixed with aluminum casting parts for cars (55% of the world).
Applying pure silicon that is ranked second as a raw material to produce silicon (40% of the world).
Pure silicon is used to produce ultrapure silicon for electronic applications as well.
Semiconductor - Ultrapure silicon can be mixed (doping) with other elements to change in response to electricity by controlling the number and charge (positive or negative) of the conductor. This is necessary for transistors, solar cells, semiconductor detectors, and other semiconductor devices used in electronics.
Photonic devices - silicon can be also used as Raman laser to produce coherent light. (However, it is inefficient light sources).
LCDs and solar cells - the amorphous silicon-hydrogen compound are widely used in electronics manufacturing, low price and with large areas such as the LCD and may also be used in solar cells, thin-film, low-cost and large area.
Steel and cast iron - a compound of silicon steel types, is used to produce cast iron by putting an alloy of iron and silicon, or silicon and calcium.
Silicon Compounds
Construction: silicon dioxide or silica in the form of sand and clay is a key ingredient of concrete and brick, which is used in the production of cement.
Pottery / ceramics - silicon is chemically resistant to heat. Used to produce high-temperature and silicate compounds used in the manufacture of ceramics and pottery.
Glass - Silica sand is the main component of glass. It can be made into a great variety and with different physical properties. Silica is the main object of producing window glass, packaging, insulation, and other helpful things.
Abrasive - silicon carbide abrasive is one of the most important abrasive.
Medical Materials - Silicones are flexible compounds, bonding a silicon - oxygen, silicon - carbon. It is used extensively as a band made of silicone breast implants and a contact lens, as well as other applications.

Product description, Product introduction:
Quartz powder is white, it is made by grinding crushed quartz ore, and the main ingredient is SiO2 The Molecular weight of quartz is 70, mohs hardness is 7, and density is 2.65 g/cm3, melting point 1730�??. Quartz is used for friction materials in order to improve the friction coefficient and brake efficiency, reduce cost.
Quartz is applicable to car disc brake, drum brake pads, clutch and wet friction material. According to the performance requirement,The recommended regular consumption of quartz is from 2% to 8%.
The character of Feldspar:
Quartz is mainly refers to quartz sandstone, quartzite and vein quartz. Quartz crisp, no cleavage, conchoidal fracture, oily luster, milky white or colored translucent or other colors.Quartz chemical stability, resistance to high temperature, acid, slightly soluble in potassium hydroxide solution. Quartz belongs to the high hardness of the filler, ordinary sand is quartzite. friction industry used quartz powder is above 200 mesh, although it increase the friction effect, it also easy to cause obvious braking noise and scratches dual surface, therefore the quartz usage in the friction material industry is not much.

We (sri venkateswara minerals) are having our own mines of quartz and quartzite located in andhra pradesh, india. Our organization is widely reputed in offering quartzite lump to our clients as they required.
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content.
*physical properties of quartzite: hardness= 6.5- 7.2 on mho's scale.
Density = 2.3 to 2.4 kg/cm3.
Porosity = low to very low.
Weather impact = resistant.
*chemical properties of quartzite: sio2 = 97.5 - 98.5%
Fe2o3 = 0.5%-1.5%
Al2o3 = 1 to 1.5%
Na2o & kro = less then 1%
Cao = Less then 0.5%
Mgo = less then 0.5%
Loi = less then 0.5%
*uses of quartzite:
Quartzite is mainlly used in ferro alloys industries for producing ferro silicon(fesi) and silicon manganese(si mn) and also used in ceramic, glass industries. Because of its hardness and high resistance it is also used as refractory material.
We provide quartzite in different sizes (0-5mm, 10-40mm, 40-60mm, 60-100mm).
And quartzite powder 100 mesh and above.
