Fused Quartz Silica Sand

Product Description

Fused Quartz Lianyungang Donghai colorful mineral products companies to use high purity quartz from fused in high temperature silica of high purity, SiO2 content, low thermal conductivity, low coefficient of thermal expansion, high insulation characteristics of chemically stable.

Fused is made of highest purity Chinese crystal Silica by electrically fusing (fusing temperature ********0℃)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.
