Fused Silica Powder
       Fused Silica Powders , made of F.Sil grains . By using our ball mills (Al2O3 Medias & Linings) , this powder is very pure and white . Our special blending systems and analysis instruments ensure the powders a very consistent distribution and chemical stability . The low thermal conductivity and excellent thermal shock resistances makes Fused Silica Powder widely used in Foundry , Ceramics , Refractories and as ideal fillers in EMC ,      Electronic Seal , Paints & Coats industries etc . 
       Main Applications 
       Electronic Seal , EMC 
       Investment Casting 
       Refractory , Technical Ceramic 
       Paints & Coats industries
