Product Description

Chem&Size minerals is manufacturer of fused silica which is produced by melting high purity natural silica sand(quartz sand)  at 2200ºC 12 hours. In the fusing process, the crystalline phase of silica sand transforms into amorphous phase. After cooling, Fused silica ingot  is made out with high purity amorphous silicon oxide. Fused silica ingot is separated into 5-10cm lumps Grade A, Grade B and Grade C according to the black point size.

Fused silica can be used to make crucibles that produce solar cells board in the photo-voltaic industry.
Fused silica is used to make rollers, castables, mortars, gunning mixtures and forming tools in the glass industry.
Fused silica is used to make technical ceramic in the thermal resistance industry.
Fused silica is used to make ceramic slurry in investment casting industry.
Fused silica is used to make Acidic acid refractory,Fused silica precast shapes,Fused silica big blocks and fused silica castables
