Description

Metal silicon powder is powdered silicon powder obtained by grinding metal silicon (industrial silicon).

Metal silicon, 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, a deoxidizer for smelting special steel grades and non-ferrous alloys. After being processed by a series of processes, industrial silicon can be drawn into monocrystalline silicon for use in the electronics industry.

The composition of metal silicon is mainly silicon, so it has similar properties to silicon. The properties of metal silicon are similar to those of germanium, lead and tin, and have semiconductor properties.

The classification of metal silicon is usually classified according to the content of three main impurities of iron, aluminum and calcium contained in the metal silicon component. According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades.

made available
 
1. Industrial silicon powder is widely used in refractory materials and powder metallurgy industries to improve the high temperature resistance, wear resistance and oxidation resistance of products. Its products are widely used in steelmaking furnaces, kilns and kiln furniture.

2. In the organosilicon chemical industry, industrial silicon powder is the basic raw material for organosilicon polymer synthesis, such as the production of silicon monomers, silicone oil, and silicone rubber preservatives, thereby improving the product's high temperature resistance, electrical insulation, and corrosion resistance. properties, anti-corrosion, waterproof and so on.

3. Industrial silicon powder is drawn into monocrystalline silicon, and the processed silicon wafer is widely used in high-tech fields and is an indispensable raw material for integrated circuits and electronic components.

4. In the metallurgical casting industry, industrial silicon powder is used as a non-ferrous alloy additive and a silicon steel alloy agent to improve the hardenability of steel. Industrial silicon powder can also be used as a
reducing agent for certain metals, for new ceramic alloys, etc.
