Production process of metal silicon：
The production of metal silicon adopts the carbothermal method, that is, the method of smelting in submerged arc furnaces with silica and carbonaceous reducing agents. Silica is used as the raw material, petroleum coke, charcoal, wood chips, low ash coal, etc. are used as the reducing agent, and it is smelted at high temperature in a submerged electric furnace to reduce metal silicon from the silica, which is a slag-free submerged arc high-temperature smelting process.

Uses of silicon metal：

Silicon metal is industrially purified elemental silicon, which is mainly used for the production of organic silicon, the preparation of high-purity semiconductor materials, and the preparation of alloys for special purposes.

Modern large-scale integrated circuits that manufacture high-purity semiconductors are mostly made of high-purity metal silicon, and high-purity metal silicon is the main raw material for the production of optical fibers. Metal silicon can be said to be the basic industry in the information age.
Production of silicone rubber, silicone resin, silicone oil and other silicone rubber, good elasticity, high temperature resistance, used in the production of medical supplies, high temperature gaskets, etc. Silicone resins are used in the manufacture of insulating coatings, high-temperature coatings, etc.
The compounded alloy silicon-aluminum alloy is the silicon alloy with the largest amount. Silicon-aluminum alloy is a strong composite deoxidizer. It can replace pure aluminum in the steelmaking process to improve the utilization rate of deoxidizer, purify molten steel, improve steel quality, and prolong service life. It is often used to produce aerospace vehicles and auto parts. Silicon-copper alloy has explosion-proof function and can be used to make storage tanks.
