Brief introduction：
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. Silicon aluminum alloy is a strong composite deoxidizer, which can replace pure aluminum in the process of steelmaking, improve the utilization rate of deoxidizer, purify liquid steel and improve the quality of steel.
* Industrial silicon, as an additive to non-ferrous alloys, is also used as an alloying agent for silicon steel with strict requirements, and as a deoxidizing agent for smelting special steel and non-ferrous alloys.
* Chemical, used for the production of silicone rubber, silicone resin, silicone oil and other silicone, silicone rubber elastic, high temperature resistance, used in the production of medical supplies, high temperature resistance gaskets. Silicone is used in the production of insulating coatings and high temperature coatings.
* Industrial silicon is purified through a range of processes to produce polysilicon and monocrystalline silicon for the photovoltaic industry and the electronics industry.
