Fused silica
1.Introduction
Fused Silica is manufactured from silica sand, through high temperature fusion, cooling, smash and selecting. The powder is produced 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 content. Mainly applied in plastic seal used in large-scale and extra large-scale integrate circuit, epoxy resin, pouring, quartz rubber and other chemical industries.
