Product 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.

Product nature

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.

Product category

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.

Additional Products

Including silicon powder, edge skin silicon, black skin silicon, metal silicon slag, etc. Among them, silica micropowder is also called silica fume, micro-silica fume or silica fume, which is widely used in refractory materials and concrete industries.

Product Usage

1. Metal 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, metal 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 high temperature resistance, electrical insulation and corrosion resistance of products. properties, anti-corrosion, waterproof and so on.
3. Metal silicon powder is drawn into single crystal 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, metal 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.
