Fused Silica

Fused silica is manufactured from silica sand, through high temperature fusion, cooling, smash,and selecting. The powder is made from fused silica lump, it is powder of high purity and amorphous. It is charactered by its low linear eapansion coefficient, low stress and low radioactivity.
