Silicon metal powder is silicon metal (industrial silicon) after grinding and processing of powder silicon powder.
Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Industrial silicon is also used as an alloying agent for demanding silicon steel, smelting special steel and deoxidizer for non-iron based alloys. Industrial silicon can be drawn into monocrystalline silicon after a series of processes for use in electronics industry.
Nature of the product
Silicon metal is composed mainly of silicon and thus has similar properties to silicon. Silicon metal has semiconducting properties similar to germanium, lead and tin.
Product categories
Silicon metal is usually classified according to the content of iron, aluminum and calcium, the three main impurities contained in the silicon metal composition. According to the content of iron, aluminum and calcium in silicon metal, silicon metal can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades.
Product use
1, metal silicon powder is widely used in refractory materials, powder metallurgy industry, in order to improve the product's high temperature resistance, wear resistance and oxidation resistance. Its products are widely used in steelmaking furnaces, kilns and kiln tools.
2, in the organic silicon chemical industry, metal silicon powder is the basic raw material for the synthesis of organic silicon polymer, such as used for the production of silicon monomer, silicone oil, silicone rubber preservatives, so as to improve the product's high temperature resistance, electrical insulation, corrosion resistance, corrosion resistance, waterproof and other characteristics.
3, metal silicon powder by drawing made of monocrystalline silicon, processed silicon wafers are widely used in the field of high-tech, integrated circuits, electronic components essential raw materials.
4, metallurgical casting industry, metal silicon powder as non-ferrous alloy additives, silicon steel alloy agent, so as to improve the hardenability of steel. Industrial silicon powder can also be used in some metal reducing agent, used in new ceramic alloys, etc.Bulk Deoxidizer
