Silicon Metal, also known as industrial silicon, is a product produced by smelting silica and carbon based reducing agents in a submerged arc furnace. The main component silicon content is usually above 98.5%, below 99.99%, and the remaining impurities are iron, aluminum, calcium, and so on.
Mainly used in semiconductor, alloy, silicone polymer materials. High purity monocrystalline silicon is an important semiconductor material. Used as diodes, transistors, thyristors, and various integrated circuit materials. It is also a promising material in the development of energy, and can be used to manufacture solar cells, etc. Mixing and sintering ceramics and metals to produce a cermet composite material, which is resistant to high temperatures, rich in toughness, and can be cut. It combines the advantages of metals and ceramics, and is an important material for cermet and space navigation. High transparency glass fiber made from pure silicon dioxide has high optical fiber communication capacity, is not subject to electrical and magnetic interference, and has a high degree of confidentiality, which can be used for optical fiber communication. Silicone organic compounds have been widely used as plastics, coatings, etc.
