The raw material of metallic silicon
Apr 17, 2025
What are the raw materials for the production of metallic silicon?
1. Raw materials for the production of metallic silicon
The raw materials for the production of metallic silicon are mainly quartz ore and coal. Among them, quartz ore is the main raw material for metallic silicon, while coal is used as a reducing agent. Quartz ore is a mineral containing silicon dioxide, whose main component is SiO2, and is one of the raw materials for the production of metallic silicon. Coal is a carbon-containing fossil fuel and a reducing agent in the production of metallic silicon.
2. Production process of metallic silicon
The production process of metallic silicon includes two processes: refining and purification. The refining process refers to the reduction reaction of quartz ore and coal at high temperature to produce metallic silicon and by-product brightener. The purification process is to purify the refined metallic silicon to achieve industrial purity. The purification process mainly includes two methods: chlorination method and silane method.
3. Application fields of metallic silicon
Silicon metal is widely used in metallurgy, electronics, chemical industry and other fields. In the metallurgical industry, metallic silicon is an important raw material for the manufacture of silicon steel; in the electronics industry, metallic silicon is an important basis for the manufacture of semiconductor materials; in the chemical industry, metallic silicon is an important raw material for the manufacture of organic silicon materials.
In short, the raw materials for the production of metallic silicon are mainly quartz ore and coal, and its production process includes two processes: refining and purification. Metallic silicon is widely used in metallurgy, electronics, chemical industry and other fields
