Spherical silica powder is made from irregular angular silica powder with flame melt process. The result is obtaining a spherical dioxide silica powder with less surface area, good fluidity and low stress.

With unique physical and chemical, spherical silica powder is widely used in optics, aviation, electronics, chemical industry, machinery and the rapid developing IT industry. It’s special internal molecular structures, crystal shapes and the change rules of lattice, make it having features of high temperature resistance, less thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and special optical property, which play a more and more important part in high-tech products manufacture.
