Product Description

Fused silica lumps/cullet Grade A introudce is as follows:

Fused Silica is made of high purity crystal silica from China Donghai-Xinyi by electrically fusing (fusing temperature 1800-2000ºC) to amorphous Silicon dioxide, then is specially engineered into lumps,cullet, ingots, sand,grain,granular and powder flour form designed for making PV fused silica crucible,thermal ceramic,refractory,EMC investment casting ceramic shell etc.
