Fused silica Lump introduce :
Fused silica is made of high purity crystal silica by electrically fusing (fusing temperature 1800-2000℃) to amorphous Silicon dioxide , then it was classed to different grades by manual and then specially engineered to granular and powder form. Because fused silica has a very low thermal conductivity and excellent thermal shock resistance, it is used in lots of fields of investment casting,refractory,ceramic,epoxy modling compound,fusion bounded epoxy.

Fused silica application:
Refractory, ceramic, investment casting, foundry, epoxy molding compound, fusion bounding epoxy powder coating.
