Fused Silica Grains
Product introduction
Fused Silica Grains
Fused Silica Grains , made of F.Sil cullets , by our special processing technologies , grading , crashing , sieving , magnetic separating , to be coarse grains or fine powders for different usages .
Due to Fused silica's low thermal conductivity and excellent thermal shock resistances as well as stable particle size distributions , it is widely used in Crucibles , Technical ceramics , High-grade Refractories , Investment Casting (Stucco & Slurry ) industries etc.
Main Applications
Fused Silica Crucible
Investment Casting & shell casting
Refractory , Technical Ceramic & glass materials
