Silicon is a non-metallic element, grey-blue, metallic, hard and brittle, the content of silicon is about 26% of the internal quality of the earth, common well-known brands of silicon metal block is generally based on the content of iron, aluminium, calcium three primary impurities contained in the silicon metal is classified. Based on the content of iron group, aluminium, calcium in silicon metal, silicon metal can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 1101 and other levels.
Silicon metal block use:
(1) silicone, silicone resin, methyl silicone oil and other silicon copper production and manufacturing. Silicone toughness, heat-resistant, used to make medical supplies and high-temperature gaskets. Organic silicone resin is used to produce manufacturing three anti-paint, high temperature resistant paint and so on. Methyl silicone oil is oil-soluble chemicals, viscosity by the ambient temperature is not harmful. It is used in the production of lubricants, polishing agents, liquid torsion spring, electrolytic medium liquid, etc., can also be made into a colourless transparent liquid, as a drug sprayed to the surface of the building.
(2) Production and manufacture of high-purity semiconductor materials. The vast majority of contemporary integrated circuit chips are made from high-purity silicon metal, and high-purity silicon metal is used as an important raw material for fibre optic wires. Silicon metal has become a leading industry in the information age.
(3) Making aluminium alloy. Aluminium alloy profile is a silicon alloy containing a lot of metallic silicon, silicon aluminium alloy is a strong compound deoxidizer. Replacing pure aluminium in the steelmaking process can improve the usage rate of deoxidant, purify and treat the steel liquid, and enhance the quality of steel. Aluminium has low density, low coefficient of linear expansion, good forging and wear resistance. Aluminium alloy castings forged with aluminium have high impact resistance and good compactness, which can greatly increase the service life. It is often used in the production of aerospace vehicles and automotive parts. Silicon-copper-nickel alloys have good weldability and do not easily cause fires in the event of a collision. It is fire resistant and suitable for storage tanks.
Silicon metal block substantial whole process requires more mixing, which is based on the basic principle of compressed gas. The main purpose is to improve the chemical elements in the raw material reaction kinetic model standard, accelerate the slagging rate, early removal of dirt, reduce heat loss and silicon bonding. Due to the fact that there is very little silicon metal in its natural composition, the vast majority of silicon metal in everyday life is produced by human labour.
