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.
Quartzite is a very hard rock composed predominantly of an interlocking mosaic of quartz crystals. The grainy, sandpaper-like surface is glassy in appearance. Minor amounts of former cementing materials, iron oxide, silica, carbonate and clay, often migrate during recrystallization, causing streaks and lenses to form within the quartzite. To be classified as a quartzite by the British Geological Survey, a metamorphic rock must contain at least 80% quartz by volume

Silica (SiOâ??) 97.00%
Alumina (AlO) 1.00%
Moisture 1.00%
Size 10 to 40 mm, 20 to 70 mm, 40 to 80 mm
