Description

Silicon metal is a grey and shiny semiconductor metal, also known as crystalline silicon or industrial silicon, and is mainly used as an additive for non-ferrous alloys. Silicon metal is produced from quartz and coke in an electric furnace, and the content of the silicon element is about 98% (in recent years, with a content of 99.99%, Si is also called silicon metal), and the other impurities are mainly iron, aluminium, calcium, and so on. The classification of metallic silicon is according to the content of iron, aluminium, and calcium; silicon metal can be divided into different grades such as 553, 441, 411, 3303, 2202, and 1101.

What is silicon metal grade 553?
Silicon metal 553 is a commonly used grade. In the metal silicon 553, the silicon content should be as high as 98.5%. The contents of iron, aluminium, and calcium are 0.5%, 0.5%, and 0.3% respectively. Silicon 553 and silicon 441 are mainly used in the production of aluminium ingots. Adding silicon metal to aluminium alloys makes them strong and light.
 

Silicon metal 553 specifications:
Silicon metal 553 generally the diameter is 10-50mm,50-100mm,10-100mm or other sizes as customer’s request. Silicon metal is a grey and shiny semiconductor metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys that are smelted from quartz and coke in an electric furnace.
 

Uses of Silicon metal 533 :
Silicon metal 553 is widely used in refractories, powder metallurgy industry, it is an excellent antioxidant. Adding silicon metal 553 in the refractory material can first react with oxygen to form a new mineral phase, close the pores, improve the density, and prevent the penetration of slag iron, so as to improve the product’s high-temperature resistance, wear resistance, and oxidation resistance of the product.
 

Purpose of silicon metal:
1. Use for Al alloy product: could be added in aluminium alloys, to enhance the strength of the alloy, increase its anti-oxidation and corrosion resistance, decrease its density and coefficient of thermal expansion, meliorate its casting performance, and make the alloy have a high impact resistance and pressure resistance.

2. Used for cold-rolled silicon steel products: After adding silicon metal in steel, it could greatly improve the magnetic properties of steel, increase its permeability, reducing the hysteresis and eddy current losses.

3. Use for high-purity semiconductor products: Due to the high melting point of silicon, good thermal stability, large band gap, and rich in resources, with technology has been improving, integrated circuits and large-scale integrated circuits which made from silicon semiconductors have been used in various fields, the demand is growing up year by year.

4. Use for organic silicon products: silicone, silicon resin, and silicone oil Silicone: This material maintains flexibility in the range of -700 °C to -2000 °C and could be used for high-temperature gaskets and cold insulation materials. Silicon resin: used for the production of insulating paint, a heat temperature of 180 ~ 2000℃, can also be used for the production of high-temperature coatings. Silicone oil: For the production of senior lubricant, polishing agent, fluid spring, and dielectric liquid, also could also be processed into a colourless, transparent liquid, and sprayed on the building for waterproofing. Silicon metal is more and more widely used in the organic silicon industry, the usage amount tends to exceed that of the aluminium alloy industry.

5. Use for the heat-resisting material product: For the production of Si3N4, heat-resistant, wear-resistant, and corrosion-resistant. Making the coated material can prevent oxidation. Siliconized steel surfaces can improve the corrosion resistance of the steel.
