Silica powder- Quartz powder: We are also manufacturing Silica powder. This is natural silica having purity of more than 99.7% Sio2. This silica powder comes in a very snow white color , the whiteness in A grade silica is more than 96% . Silica powder is available in 100 mesh , 200 mesh, 300 mesh, 10 microns D-97. The average particle size in Micronised Silica powder in below 5 micronsQuartz is a very hard mineral composed of silica, SiO2, found worldwide in many different types of rocks, including sandstone and granite.
