High purity quartz sand for quartz crucible


Fused Silica


Fused silica is manufactured from silica sand, through high temperature fusion,

cooling,smash, and selecting. The powder is produced using fused silica lump

as material, it’s white powder of high purity and amorphous. With the quality of

low linear expansion coefficient, low stress and low radioactivity.



The content of oxidized silicon in fused silica is above 99.99%.The Mosh hardness of

fused alumina is6.0.
