Product Name:Fused Silica - Technical Thermal Ceramic Grade  
Fused Silica - Technical Thermal Ceramic 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  granular and flour form designed for fused silica roller and other high temperature technical creamics production.
Special Features:
●  Very low coefficient of thermal expansion (0.54×10-6-1,0~1000℃)
●  Superior Heat Resistance & Chemical Resistance
●  Pure(high SiO2 content, low Fe, Na, K & Ti)
●  Consistent Chemistry
●  Statistically controlled particle size distribution
Main Applications:
●  Fused Silica Roller
●  Other High Temperature Technical Ceramics
