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.
Applications
1,Used in precision casting
2,Applied to refractory materials and optical glass production
3,Fused silica can be used for grinding wheel abrasives and high quality glass production
4,Fused stone is also a kind of electronic seal materials
5,As an ideal stuffing materials, fused silica could be used in paint and coating industry
6,Epoxy resin,pouring, quartz rubber and other chemical industries
