Product Description

Chem&size Minerals Fused Silica is high purity quartz sand which has been melted to amorphous silicon oxide(glass phase) by electrically fusing (fusing temperature 1800-2200ºC), then specially engineered  into sand/grains/granular or powder/flour form.
 
 
The characters of fused silica is as follows:
1).fused silica characterized by the lowest thermal coefficient of expansion (0.54×10-6ºC-1,0~1000ºC),high resistance to temperature and thermal shock. 
2).high Purity (high SiO2 content 99.96%, low Fe, Na, K and Ti)
3). Statistically controlled particle size distribution

Fused silica main Applications is used to make Fused Silica Roller and other High Temperature Technical thermal Ceramics.
