Product description

Industrial silicon, also known as crystalline silicon or metallic 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

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

Product category
The classification of industrial silicon is usually classified according to the content of three main impurities of iron, aluminum and calcium contained in industrial silicon components. According to the content of iron, aluminum and calcium in industrial silicon, industrial 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
Industrial silicon is used for the production of organic silicon, the preparation of high-purity semiconductor materials, and the preparation of alloys for special purposes.
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 high temperature resistance, electrical insulation and corrosion resistance of products. 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.
