Silicon metal has a wide range of uses, mainly in the following areas:
1. Semiconductor industry: Silicon metal is an important component of semiconductor materials and is used in the manufacture of electronic devices such as integrated circuits, solar panels and LEDs. Its high purity and good electronic properties make it widely used in the electronics industry.
2. Iron and steel smelting: In the metallurgical industry, silicon metal is an important alloying material. Adding the right amount to iron and steel can improve its hardness, strength and wear resistance, as well as its physical and chemical properties.
3. Foundry industry: Silicon metal can be used as a casting material to improve the toughness and thermal fatigue resistance of castings and reduce casting defects and deformation.
Silicon metal powder is an important industrial raw material that is widely used in the refractory materials and powder metallurgy industries.
In the refractory materials industry, silicon metal powder can be used to make high-grade refractory materials such as silica refractory bricks and aluminium silicate refractory fibres. These refractory materials have the advantages of high refractoriness, high strength and high toughness, and are widely used as lining materials for high-temperature industrial furnaces such as those for steel, cement and non-ferrous metals.
2. In the powder metallurgy industry: silicon metal powder can be used to make various high-performance alloy materials. For example, adding silicon metal powder to metals such as iron and nickel can significantly improve the hardness, wear resistance and corrosion resistance of the alloy. Silicon metal powder can also be used to make various electronic devices, such as integrated circuits and solar panels.
