Silicon Metal, often referred to as industrial silicon, is a single substance of silicon made from quartz (silica) by high temperature smelting. It has unique physical and chemical properties and is therefore widely used in different industries.
silicon metal physical properties
- Appearance is gray-black or silver-gray with metallic luster.
- Silicon has a high hardness, a melting point of 1414°C, and a boiling point of 3265°C. It has a relatively high thermal and electrical conductivity.
- Thermal conductivity and electrical conductivity are relatively poor, but there is some electrical conductivity at high temperatures.
silicon metal chemical properties
- Silicon is relatively stable at room temperature and does not react violently with oxygen, water, acids, etc..
- Under high temperature conditions, it is able to react with oxygen, nitrogen, hydrogen, etc. to produce silicon dioxide or silicon compounds.
- The purity of industrial silicon usually ranges from 98.5% to 99.99%, with different purity specifications according to applications and needs.
silicon metal applications
1. Alloy Manufacturing:
- Silicon metal is widely used as an alloying element in the manufacture of aluminum alloys and silicon steel. It can improve the strength, hardness and corrosion resistance of aluminum alloys. Silicon steel (such as electrical silicon steel) is used in electrical equipment because of its good magnetic conductivity.
2. Semiconductor industry:
- Silicon metal can be further purified to make electronic grade silicon, which is used in the manufacture of semiconductor devices (e.g., transistors, integrated circuits, solar cells, etc.). Ultra-high purity silicon is the basic material for semiconductor and microelectronics technology.
3. Chemical industry:
- Silicon metal is used in the production of organosilicon compounds. Organosilicon materials have excellent high-temperature resistance, corrosion resistance, insulation and waterproofing properties, and are widely used in construction, electronics, electrical appliances, automotive and other industries.
4. Solar photovoltaic industry:
- High-purity silicon metal is made into polycrystalline and monocrystalline silicon. These materials are the core of solar cells, which can effectively convert solar energy into electricity.
