Products Description
Metal silicon 97, also known as crystalline silicon or industrial silicon, is a material with important application value. Its main component silicon element content is about 98%. In recent years, products containing 99.99% Si are also classified as metal silicon 97. The remaining impurities mainly include iron, aluminum, calcium, etc. This material is mainly smelted in an electric furnace with silica and blue carbon (or coke) and has semiconductor properties.
The smelting process of metallic silicon 97 is a high-energy production process. During the smelting process, it is necessary to control the particle size, ratio of silica and semi-coke (or coke), and the temperature of the electric heating furnace and other parameters to obtain high-quality metallic silicon 97 products. However, there are still some problems in the existing smelting process. For example, when the particle size is too large, unreacted silica is easy to enter the liquid silicon, resulting in an increase in the amount of slag, difficulty in furnace discharge, reduced silicon recovery rate, and increased energy consumption. The market price of silicon metal 97 varies depending on factors such as region, brand, quality, etc. For example, in some regions, the price of silicon metal 97 may reach RMB 13,200 per ton, while in other regions it may be as low as RMB 8,000 per ton.
Metal silicon 97 is the basic material for manufacturing semiconductor devices, such as integrated circuits, solar cells, etc. Its high purity and good electrical conductivity make it an indispensable part of these devices. High-purity metal silicon 97 is also one of the main raw materials for the production of optical fibers. Optical fibers are widely used in the fields of communications and data transmission, and metal silicon 97 provides important material support for the development of optical fiber communications. Metal silicon 97 is used as an alloy additive in metallurgical industries such as steel and aluminum alloys to improve the mechanical properties, corrosion resistance and high temperature resistance of metal materials. In the steel smelting process, metal silicon 97 is often used as a deoxidizer to help remove oxygen and other impurities in steel and improve the quality of steel.
In summary, metal silicon 97 is a material with important application value and is widely used in many fields. With the continuous advancement of technology and the continuous development of the market, the application prospects of metal silicon 97 will be broader.
