fused silica /technical thermal ceramic grade

Descripción del producto

Qmin-SIL Series Fused Silica is made of high purity Chinese crystal Silica by electrically fusing (fusing temperature ********0℃) to amorphous Silicon dioxide , then specially engineered  granular and flour form designed forfused silica roller and other high temperature technical creamics production.

 

 

Special Features:

● Very low coefficient ofthermal expansion (0.*4×*0*6℃*1，0～***0℃)

● 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
