According to the content of iron, aluminum, and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101. Industrially, metallic silicon is usually produced by reducing silica with carbon in an electric furnace. Chemical reaction equation: SiO2+2C→Si+2CO The purity of silicon obtained by this method is 97~98%, which is called metallic silicon. melt it and recombine it
The classification of metallic silicon 200 mesh is usually based on the content of the three main impurities contained in the metallic silicon component: iron, aluminum, and calcium. According to the content of iron, aluminum, and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.
Industrially, metallic silicon is usually produced by reducing silica with carbon in an electric furnace. Chemical reaction equation: SiO2+2C→Si+2CO The purity of silicon obtained by this method is 97~98%, which is called metallic silicon. It is melted and recrystallized, and impurities are removed with acid to obtain metallic silicon with a purity of 99.7-99.8%.
Metallic silicon 200 mesh is a very common additive used in smelting iron alloys. In so many years of production and sales, the supplier group of metal silicon 200 mesh is mainly used by some smelters for making additives. Today we talk about where metal silicon may be used?
Metallic silicon 200 mesh is mainly used as an additive for non-iron-based alloys, and its main component is silicon. Because of this, its uses include the following:
1. Metallurgical mineral processing. The hardness of metallic silicon 200 mesh is quite high, not much worse than diamond. In addition, metallic silicon has very high wear resistance. It is an ideal material for wear-resistant pipes, impellers, pump chambers, cyclones, and mining bucket linings. Its wear resistance is very high, and its service life is 5-20 times that of cast iron, rubber, etc.
2. Steel industry. Because metallic silicon 200 mesh has strong corrosion resistance, high impact resistance, and good wear resistance. Another very important point is the good thermal conductivity of metallic silicon. Therefore, many large blast furnaces also use metallic silicon as furnace linings. Can greatly increase its service life.
3. Ceramic building materials. We can use the 200 mesh thermal conductivity, thermal radiation and high thermal intensity of metallic silicon to manufacture thin plate kiln furniture. This can not only reduce the production capacity of kiln furniture, but also improve the production capacity and product quality of kiln furniture, and shorten the production cycle. It is an ideal raw material for ceramic glazes.
