   Product Name:Fused Silica - PV Crucible Grade  
 
  
Fused Silica - PV Crucible Grade   
 
Qmin-SIL Series Fused Silica is made of high purity Chinese crystal Silica by electrically fusing (fusing temperature 1800-2000℃) to amorphous Silicon dioxide , then specially engineered ingots, granular and flour form designed for making PV fused silica crucible.
 
 
Special Features :
●  Very low coefficient of thermal expansion
●  Superior Heat Resistance
●  Pure(high SiO2 content, low Fe, Na, K & Ti)
●  Consistent Chemistry
●  Statistically controlled particle size distribution
 
Main Applications :
● Fused Silica Crucible PV industry
● Other High Temperature Technical Ceramics
