Fused Silica Lump Third Grade(Also called C grade block)

Short Description:

Fused Silica Lump Third Grade(Also called C grade block)

High purity quartz stone in Lianyungang and Xuzhou area was selected as raw material. After pickling treatment, the crystalline silica was transformed into amorphous silica with a small amount of impurity at 1700ºC high temperature in the resistance furnace. After special mechanical processing, screening, iron removal after after picking treatment of high purity quartz stones for the formation of blocks, particles and powder products.
