What is the difference between ferro silicon and silicon metal?
Views: 2746 Update date: Apr 11,2023
Ferro silicon and silicon metal are two commonly used alloys in the metallurgical industry. Both of these materials are made up of silicon, which is a chemical element that has the symbol Si and atomic number 14. However, there are some significant differences between ferro silicon and silicon metal in terms of their composition, properties, and uses.
Composition:
Ferro silicon is an alloy of iron and silicon. It typically contains between 15% and 90% silicon and small amounts of other elements such as carbon, phosphorus, and sulfur. The amount of silicon in ferro silicon determines its properties, such as its melting point, density, and hardness. The composition of ferro silicon can vary depending on the specific application it is intended for.
Silicon metal, on the other hand, is a pure form of silicon. It is produced by heating quartz and carbon in an electric furnace at very high temperatures. The resulting material is a crystalline structure that is nearly 100% silicon. Silicon metal is often used as a raw material for the production of other silicon-based materials such as silicones, silanes, and semiconductors.
Properties:
Ferro silicon is a hard and brittle material that is resistant to corrosion and oxidation. It has a high melting point and density, making it suitable for use in steelmaking, cast iron production, and other industrial applications. Ferro silicon is also a good source of silicon for the production of silicon-based alloys.
Silicon metal, on the other hand, is a shiny, silver-gray material that is extremely pure and has a high melting point. It is an excellent conductor of heat and electricity and is often used in the production of electronic components such as computer chips, solar cells, and semiconductors. Silicon metal is also used as an alloying agent in the production of aluminum and steel.
Uses:
Ferro silicon is primarily used as an additive in steelmaking and cast iron production. It is added to molten iron to improve its properties such as strength, hardness, and resistance to corrosion. Ferro silicon is also used in the production of other alloys such as silicon manganese, silicon aluminum, and silicon bronze.
Silicon metal is used in a wide range of applications. Its excellent electrical conductivity makes it a key material in the production of electronic components such as computer chips, solar cells, and semiconductors. Silicon metal is also used in the production of aluminum alloys, which are used in the automotive and aerospace industries. Additionally, it is used as a raw material for the production of silicones, silanes, and other silicon-based materials.
