Chem&Size minerals is manufacturer of fused silica/fused quartz which is produced by melting high purity natural silica sand(quartz sand)  at 2000ºC 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.

China fused silica is an amorphous silicon oxide or silica glass which is produced by high temperature fusion of high quality natural quartz(crystalline silica).This melting produces fused silica characterized by the lowest thermal expansion,high resistance to temperature and thermal shock.
