Amorphous Silicon dioxide (Fused Quartz Silica)
Colorful Mineral Product Company of amorphous Silicon Dioxide Fused Silica is made of highest purity Chinese Donghai local crystal Silica by Burning or electrically fusing (fusing temperature 1800-2000℃)to amorphous Silicon dioxide quartz silica , then specially crushing and processing to Quartz Silica ingots, granular and flour powder form for different usage.
This amorphous Fused Silica Quartz Silicon Dioxide has a very low thermal conductivity and excellent thermal shock resistance.
