Fused silica is manufactured from silica sand, through high temperature fusing, cooling, smash and selected. The powder is produced by using fused silica lump as material. It's white powder of high purity and amorphous with the quality of low linear expansion coefficient, low stress and low radioactivity.

High content of SiO2 could exceed 99.9%
