High purity fused silica sand

INTRODUCTION & CHARACTORS:

Fused Silica is produced from high purity natural silica stone, melted at extremely temperature to create high purity, high SiO2 composition, high electrical resistance, lowest thermal expansion and exceptionally good thermal shock resistance.

 

APPLICATION:Fused Silica is used mainly in refractories, epoxy molding compounds, investment castings, ceramics, shell moulds, silicon rubbers, and electrical insulators.
