Silicon products mainly have the following uses:

Deoxidizer. In the steelmaking process, oxygen in the molten steel is removed, and some ferroalloys can also remove other impurities such as sulfur and nitrogen in the steel.
Alloy additives. According to the requirements of the steel composition, alloy elements are added to the steel to improve the performance of the steel.
Inoculant. Add molten iron before casting iron to improve the crystalline structure of the casting.
Reducing agent, reducing agent for producing other ferroalloys and non-ferrous metals by metal thermal reduction method; alloy additive for non-ferrous alloys; also used in small amounts in chemical industry and other industries.

  Silicon Slag

  Silicon slag is a subsidiary product of metal silicon smelting, the silicon content is generally 30-70%.
  Silicon slag use: Silicon slag can be used for recrystallization and purification in the middle; effective slag discharge, increase the label, improve the toughness of the casting and the cutting ability And output.

  Ferrosilicon

  Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is a ferrosilicon alloy made of coke, steel shavings, quartz (or silica) as raw materials and smelted in an electric furnace. Since silicon and oxygen can easily synthesize silicon dioxide, ferrosilicon is often used as a deoxidizer during steelmaking. At the same time, a large amount of heat is released when SiO₂ is generated. While deoxidizing, it is also beneficial to increase the temperature of the molten steel.

  Silicon Metal

  Silicon metal is a product made by smelting quartz and coke in an electric furnace. The main component silicon element content is about 98% (Si content 99.99% is also contained in metal silicon), and the remaining impurities are iron, aluminum, calcium, etc. Semiconductor silicon is used to make high-purity metal silicon for semiconductor devices. It is sold in the form of polycrystalline and single crystal, the former is cheap, the latter is expensive. Because of its different uses, it is divided into various specifications.
