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
