Description
Fused quartz sand is colorless, transparent, massive, granular or white powder. It uses Donghai local high purity quartz as raw material, and produces amorphous silica by electro melting (the temperature of electro melting reaches 1800-2000 degrees Celsius). Then it is processed by special machine to remove impurities, screen and produce as bulk, granular and powdery products. It has the characteristics of high purity of silica, high content of SiO2, low thermal conductivity and excellent thermal stability, extremely low coefficient of thermal expansion, high insulation, and stable chemical properties.
