Fused Silica

Fused Silica is made of highest purity crystal Silica by electrically fusing (fusing temperature 1800-2000℃) to amorophos Silicon dioxide, then specially engineered ingots, granular and flour form designed for different usage. This product has a very low thermal conductivity and excellent thermal shock resistance
