DESCRIPTION
silicon carbide is a versatile material that finds use in a wide range of industrial and technological applications due to its unique combination of properties.
Abrasives: Silicon carbide is used as an abrasive in grinding wheels, sandpaper, and other abrasive products.
Refractories: Silicon carbide is used as a refractory material in high-temperature applications, such as furnace linings and kiln furniture.
Semiconductor devices: Silicon carbide is used in high-power electronics, such as power supplies, electric vehicles, and solar inverters.
Foundry applications: Silicon carbide is used as a mold material in foundry applications, due to its high thermal conductivity and resistance to thermal shock.
Wear-resistant parts: Silicon carbide is used to make wear-resistant parts, such as pump seals, bearings, and nozzles, due to its high hardness and resistance to wear.
