Description

Also known as ground quartz and silica flour, is produced by grinding high-purity quartz, quartzite, sandstone, or silica sand to finer than 45 micron. Air separation is used as required to remove kaolin, mica, feldspar, or calcite impurities. 
we can crush also reach 45 micron with magnetic separation
Uses: 
1- glass industry
2- lenses industry
3- television, radio, computer, radar, transmission machine industry
4-pure quartz for photocells
5- semi conductor industry
6-Cleaners
7-Paint 
8-cramics: Low-iron ground silica, typically -200 mesh, and calcined silica are used in whiteware formulations to facilitate drying of the body, to control expansion characteristics and compatibility between the body and glaze to prevent crazing, and to provide whiteness and acid resistance.
10-Coatings Ground quartz and novaculite are used as extender pigments because of their low binder demand, which allows high loadings. 
11-Rubber Finer (<0.025 micrometer) precipitated silica is the only fully reinforcing alternative to carbon black for general rubber compounding. Most of the precipitated silicas used in rubber are reinforcing grades rather than the coarser extending grades. Precipitated silica is used in compounds designed to be translucent or colored, and in general compounding to promote abrasion resistance, cut growth resistance, tear strength, elastomer-to-textile adhesion, and resistance to heat aging. 
12- Plastics: are used as thixotropes in unsaturated polyester resins and gel coats and in epoxy resins. Fumed and precipitated silicas are used as thixotropes in PVC plastisols. used as ant blocking and antislip agents by temporarily absorbing plasticizers that can cause tack and by providing an imperceptible surface roughness. They are used as matting or flatting agents and as plate-out agents in highly plasticized compounds.
