Ceramic Ball Valves for Polysilicon Industry

Polysilicon is produced from metallurgical grade silicon powder by a chemical purification process, and metallurgical grade silicon, also called MG-Si, is obtained by using SiO2 as raw material. In this process, the raw material and mid-products include silicone powder, Hydrogen chloride gas (HCL), Silicon tetrachloride (SiHCl3, STC), Silicon tetrachloride (SiCl4), Dichlorosilane (SiH2Cl2), Hydrogen (H2).

Silicon powder is high abrasive and wet HCL gas is very corrosive and dangerous for health and environment. While H2 gas is also dangerous since flammable and explosive. Valves play a very important role in these polysilicon production process, and corrosion-resistance, abrasion-resistance, high quality, and longer working life are all required to improve the stability and reduce maintenance.
