High Purity Chemical Grade Silicon 3303#

We produce high-purity chemical and metallurgical grade silicon metal and have below advantage. Low P, B content without any additional treatment owe to high quality raw material. Suitable to produce poly-silicon.P <= 20ppm, B <= 8ppm.Consistent quality with SGS ISO 9001 certification as early as 2001. We have 4 sets of 12,500KVA furnaces whose capacity ensure you a steady composition Silicon metal in one batch. Furthermore, one Xseries ICP-MS was equipped to analyze trace elements to fulfill the special requirement from customers.Continuously supply We will never suspend production due to restricted power supply during dry season, which ensure the continuous supply on our products.Our silicon metal is used by the chemical industry in the production of silicone compundsand by aluminum manufacturers to improve the useful properties of aluminum, as well as in the manufacture of silicon wafers used in photovoltaic solar cells and electronic semiconductors.
