Fused Silica sand XRD Report:
Top Quality Fused Silica Sand for Refractory/Investment Casting/EMC/Fbe


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.

Fused Silica sand Appearance  and Specifications:

1): It is forbidden to contain any unfused parts. 

2): It is forbiden to have Foreign material, such as string, plastic line, carbon or wooden material, metal or other outside contaminants.

3): All color dots is forbidden except conditional black dots

4): It is not acceptable that black spot diameter is larger than 2mm.

5): Total black dots quantity should be less than 10 when opening the big bag equal or less than 10 dots per
square meters
