High Purity Organic Silica Powder Pure Silica Powder Fused Silica Powder

Quartz sand has unique physical and chemical characteristics, which make it play an important role in the aviation,  aerospace, electronics, machinery and today's rapidly developing IT industry. Especially its internal molecular chain structure, crystal shape and lattice change rule make it have high temperature resistance, low thermal expansion  coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical  characteristics, which play an increasingly important role in many high-tech products.
