DESCRIPTION
Metallurgical silicon metal is used in a variety of applications due to its high strength, corrosion resistance, electrical conductivity, and thermal conductivity. It is commonly used in the production of castings, such as engine blocks, cylinder heads, and other components. Additionally, it is used in the production of semiconductors, solar cells, and other electronic components. It is also used in the production of steel and other alloys, as well as in the production of welding rods and other welding materials.
Metallurgical grade silicon metal applications:
- Aluminum alloys: Metallurgical grade silicon metal is used to produce aluminum alloys. It is added to molten aluminum to improve its strength, durability, and heat resistance. Silicon metal also improves the casting properties of aluminum alloys.
- Semiconductors: High-purity silicon metal is used in the production of semiconductors. It is used to create silicon wafers, which are the foundation of many electronic devices, including computers, smartphones, and televisions.
- Solar panels: Silicon metal is also used in the production of solar panels. It is used to make photovoltaic cells, which convert sunlight into electricity. The high purity of silicon metal is important in this application, as impurities can reduce the efficiency of the solar panel.
- Chemicals: Silicon metal is used in the production of a variety of chemicals, including silicones, silanes, and silicates. These chemicals are used in a wide range of industrial applications, including adhesives, coatings, and lubricants.
- Refractories: Silicon metal is also used in the production of refractories, which are materials that can withstand high temperatures and are used in the construction of furnaces and kilns. Silicon metal is added to refractory materials to improve their strength and durability.
- Steelmaking: Silicon metal is used in steelmaking to remove oxygen and other impurities from the steel. It is also used as a deoxidizer and a desulfurizer in the production of steel.
