Silicon metal 2202 is a common metal silicon product with a silicon content of greater than or equal to 99.58%. Silicon is useful in refractory materials and powder metallurgy industries and is an excellent antioxidant. For the same reason, adding metallic silicon to refractory materials can improve the product’s high temperature resistance, wear resistance and oxidation resistance. Therefore, it is very useful in refractory materials such as steelmaking furnaces, kilns, and kiln furniture. As a result, in the metallurgical casting industry, metallic silicon is a non-ferrous alloy additive and silicon steel alloy agent to improve the performance of aluminum alloys and steel.

Typically, silicon metal is produced from the reduction of silica (SiO2) with carbon in an electric arc furnace. The resulting silicon metal is then further going through refinning process for various applications. The grade of silicon metal can vary based on factors such as purity, grain size , and other specifications. Generally, there are metallurgy grade silicon, chemical grade silicon, and high-purity silicon metal.

Silicon Metal Models and Grades

Metallurgy grade silicon includes Silicon 553, Silicon 441, Silicon 3303, etc. High-purity silicon metal usually contain Silicon 99.9% or even higher. As a leading silicon metal supplier, Anyang Highrise Metal Material Co., Ltd. provides full range of silicon models. Of course, Si 2202 is one of the models. Different sizes of Silicon 2202 is opional. Such as lumps, grains, powder or fine powders. It’s all up to the customers requirement.

2202 metallic silicon will be pure through a series of processes to produce polycrystalline silicon and monocrystalline silicon, which are common in the photovoltaic industry and the electronics industry. Thereafter, crystalline silicon cells are mainly used in solar rooftop power stations, commercial power stations and urban power stations with high land costs. They are currently the most mature and widely used solar photovoltaic products, accounting for more than 80% of the world’s photovoltaic market. Their demand for metallic silicon The growth rate is obvious.
