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.
