Fused Silica Second Grade (also known as B) 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 1800ºC high temperature in the resistance furnace. After special mechanical processing, screening, iron removal after the formation of blocks, particles and powder products.
