Crystalline silica powder

I. Overview of crystalline Silica: Crystalline Silica is the use of high-grade natural quartz, processed through a unique process to produce iron-free grinding, the color white, pure quality. Its mature technology and has a stable physical and chemical properties and reasonable and controllable particle size distribution. Crystalline silica powder can be divided into high purity crystalline silica powder, crystalline silica powder and general electronic grade crystalline silica powder filler level. Use of crystalline silica powder. Second, crystalline silica powder manufacturing process: Crystalline silica powder is made from high quality quartz stone broken by the rough, a variety of pickling, milling, water treatment, drying, magnetic separation, shaping, sieving and other process with the size Silica, SiO2≥99.5-99.9%, Fe2O3≤0.008-0.03% with high purity, low conductivity and other characteristics, our annual production up to 10,000 tons.
