DESCRIPTION
Silicon metal is a shiny, grayish-colored material that is an elemental form of silicon, a chemical element with the symbol Si and atomic number 14. It is produced by heating silica and carbon in an electric furnace, and it is commonly used in the production of various materials, including semiconductors, solar cells, and alloys.
Silicon metal is used in a variety of applications, including:
- Semiconductors: Silicon is the most commonly used material in the production of computer chips and other electronic devices.
- Solar panels: Silicon is a key component in the manufacturing of solar panels, which convert sunlight into electricity.
- Alloying agent: Silicon is added to aluminum and other metals to improve their strength, hardness, and resistance to corrosion.
- Chemicals: Silicon is used in the production of various chemicals, such as silicone, which is used in a wide range of applications including lubricants, adhesives, and medical devices.
- Glass production: Silicon is used to produce glass, especially for the manufacturing of high-quality optical lenses.
- Refractories: Silicon is used as a refractory material in the production of high-temperature resistant materials, such as furnace linings and crucibles.
