the classification of metallic silicon
Metal silicon can be divided into many types according to application fields and purity grades, among which the following are the more common ones:
1. Electronic grade metallic silicon: The purity is as high as 99.9999%, which is mainly used for manufacturing electronic components, such as solar cells and semiconductor devices.
2. Industrial grade metallic silicon: The purity is above 99.5%, which is mainly used in the fields of casting, smelting and chemical industry.
3. Metallurgical grade metallic silicon: the purity is about 90%, which is mainly used for smelting metallic iron and copper.
4. Chemical grade metallic silicon: The purity is above 98%, which is mainly used for manufacturing in silicone.
the characteristics of metallic silicon
Metal silicon has high chemical stability and thermal stability, and can be used for a long time at high temperature. At the same time, it has excellent electrical conductivity and optical properties, and is an ideal material for manufacturing electronic components and optical devices. In addition, metallic silicon has high hardness and corrosion resistance, and is suitable for manufacturing wear-resistant and corrosion-resistant
parts.
the application field of metallic silicon
Because of its excellent performance, metallic silicon is widely used in the following fields:
1. Electronic field: used for manufacturing semiconductor devices, solar cells, display devices, etc.
2. Optical field: used for manufacturing lasers and optical fiber communication devices.
3. Chemical field: used for manufacturing silicone and silicone rubber.
4. Metallurgical field: used for smelting metallic iron and copper, etc.
In a word, metallic silicon is a very important industrial raw material, which is widely used in electronics, optics, chemistry and other fields. With the continuous development of science and technology and industry, the application field of metallic silicon will be more and more extensive.
