DESCRIPTION
Silicon metal is a grey, shiny, brittle, and hard material that is a chemical element with the symbol Si and atomic number 14. It is the second most abundant element in the earth’s crust, after oxygen, and is commonly found in minerals such as quartz, feldspar, and mica. Silicon metal has a high melting point and is a good conductor of electricity, which makes it an important material in the electronics industry. It is also highly reactive with oxygen and readily forms silicon dioxide, which is a major component of sand and glass. Silicon metal is produced by reducing silica, typically from quartz, with carbon in a furnace, and the resulting product is purified by various processes to achieve the desired purity levels required for different applications.
Silicon metal is a versatile material with various uses, including:
- Semiconductor manufacturing: Silicon is the primary material used to make computer chips and other electronic devices.
- Aluminum production: Silicon is added to molten aluminum to improve its strength and durability.
- Solar panel production: Silicon is used to make the photovoltaic cells that convert sunlight into electricity in solar panels.
- Chemical production: Silicon is used to produce various chemicals, such as silicones, which are used in a variety of applications, including lubricants, adhesives, and medical implants.
