Specifications of Silica Powder Sand
Use in abrasive, glasswork, cast steel, precision foundry,sand blasting, remove rust, charging, refractory, pesticide use, rubbe

Fused Silica is made of high purity Chinese crystal Silica by electrically fusing (fusing temperature 1800-2000 degrees centigrade) to amorphous Silicon dioxide, then by alumina ball mill grinding, unique air classifying, screening, magnetic and other impurity seperating techonology, designed for EMC and other electrical application.

Use in abrasive, glasswork, cast steel, precision foundry,sand blasting, remove rust, charging, refractory, pesticide use, rubber,dope, waterproof, antisepticise, abrasive ground, made ground, water treat, felt and so on.
