Coating quartz is amorphous silicon dioxide made with special process of electric melt, crash, sorting and purification. 

With unique physical and chemical characteristics, coating quartz is widely and importantly used in optics, aviation, electronics, chemical industry, machinery and the rapid development of IT industry. Especially it’s special internal molecular structures, crystal shapes and the change rules of lattice make it has features of high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and special optical property, which play more and more important parts in high-tech products.
