Fused Silica
Fused Silica is made of high purity Chinese crystal Silica by electrically
fusing (fusing temperature 1800-2000 degrees centigrade) to amorphous Silicon dioxide, then by alumina
ball mill grinding, unique air classifying, screening, magnetic and other
impurity seperating techonology, designed for EMC and other electrical
application.
