What is Metallurgical grade Silicon Carbide SIC 90 grain used for?

Metallurgical grade silicon carbide (SiC) with 90% purity is commonly used as an abrasive material in various industrial applications. Some specific uses include:

1. Abrasive Blasting: SiC grains are used in abrasive blasting processes for surface preparation, cleaning, and finishing of metal, glass, and ceramic surfaces. Its hardness and abrasive properties make it effective for removing surface contaminants and achieving desired surface textures.
2. Refractory Industry: SiC is utilized in refractory materials due to its high melting point, thermal conductivity, and resistance to thermal shock. It's used in the production of refractory bricks and shapes for lining furnaces, kilns, and other high-temperature applications.
3. Foundry Industry: In foundries, SiC grains are added to molding and core sands to improve the properties of the molds and cores used in metal casting processes. It helps to enhance the thermal stability, strength, and resistance to metal penetration of the molds.
4. Abrasive Wheels and Grinding: SiC is used as an abrasive material in the manufacturing of abrasive wheels, grinding wheels, and abrasive papers for grinding, cutting, and polishing applications in metalworking, woodworking, and other industries.
5. Ceramics Industry: SiC is used as a raw material in the production of advanced ceramics and ceramic matrix composites due to its high strength, hardness, and thermal conductivity. These ceramics find applications in aerospace, automotive, and industrial sectors.
6. Metallurgical Applications: SiC can be used as a deoxidizing agent in steelmaking and cast iron production to remove impurities and improve the mechanical properties of the final metal product.
7. Chemical Industry: SiC is used in the chemical industry as a catalyst support material and in the production of certain chemicals and petrochemicals.
