Factory price silicon metal grade

Silicon has obvious non-metallic properties. Metallic silicon smelting is a high energy-intensive production. It can be dissolved in alkali metal hydroxide solution. There are two allotropes of amorphous silicon and crystalline silicon.

Crystalline silicon is gray-black, amorphous silicon is black, and silicon is in the earth's crust, and the content of silicon is the most abundant element except oxygen, because the main part of the earth's crust is composed of silicon-containing rock layers. In nature, silicon usually exists in the form of oxygen-containing compounds. Among the metal silicon used in chemistry, silicon has relatively high requirements, requiring less impurities in silicon, and also requiring it to have good mechanical strength and thermal stability. , When chemical metal silicon is used, it contains impurities and adhesives in silicon oxide minerals.

During the smelting process, some have been completely reduced, and some have not been reduced, and some have entered in the form of compounds. Silicon or slag is generated, which not only increases energy consumption, but also reduces product quality and causes difficulties in the smelting process. Therefore, the requirements for chemical silicon are still relatively strict. Silicon metal has a wide range of applications, for example, it can be used as a deoxidizer or reducing agent. With the tightening of national energy policies, the development of energy conservation and emission reduction, and the promotion of new energy, metal silicon smelting has become a Primary products and processes.
