The product has stable chemical properties, acid and alkali resistance, high temperature resistance, wear-resistance, small expansion coefficient, high purity, high insulation and so on. It has very low thermal conductivity and conductivity, excellent thermal stability.

Amorphous silica SiO2 with high purity gangue as raw material and fused by melting at high temperature (melting temperature up to 1720-2300℃).

According to different uses, manual selection, crushing, classification, removal of miscellaneous, sieving, production of lump (fused silica block), granular (fused silica sand) or powder - like (fused silica powder) products are processed with a granular (fused silica) or special machine.
