Customizable High Purity 331 441 553 2202 Silicon Metal

Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-du fe-based zhi gold. Silicon is a nonmetallic element with grey dao color, metallic color, hard and brittle. The silicon content accounts for about 26% of the crust's mass. Atomic weight is 28.80; The density was 2.33g/m3. The melting point is 1410. Features and usage： * Metallic silicon is used in the aluminum alloy industry. Si-al alloy is a kind of strong compound deoxidizer, which can replace pure aluminum in steelmaking process to improve the utilization ratio of deoxidizer, purify liquid steel and improve the quality of steel. * As an additive to non-ferrous alloys, industrial silicon is also used as an alloying agent for silicon steel with strict requirements, and as a deoxidizer for smelting special steels and non-ferrous alloys. * Chemical industry, used for the production of silicone rubber, silicone resin, silicone oil and other organic silicon, silicone rubber good elasticity, high temperature resistance, used for the production of medical supplies, high temperature resistant gaskets. Silicone used in the production of insulation paint, high temperature coating. * Industrial silicon is purified by a series of processes to produce polysilicon and monocrystalline silicon for use in photovoltaic industry and electronic industry.
