Besides being used as an abrasive, black silicon carbide finds extensive applications in various fields. Its stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and excellent wear resistance make it highly versatile. Functional ceramics, refractories, abrasives, and metallurgical raw materials are some of the areas where black silicon carbide is predominantly utilized.
Expanding its utility further, silicon carbide can also be employed in other ways. By applying a coating of silicon carbide powder using a specialized process, the wear resistance of hydraulic turbine impellers or cylinders can be enhanced significantly. This treatment extends the service life of the turbine components by approximately 1 to 2 times. Additionally, silicon carbide serves as a high-grade refractory material that offers exceptional heat shock resistance. Its small volume, light weight, high strength, and energy-saving characteristics contribute to its efficacy as a refractory material.
To summarize, black silicon carbide serves not only as an abrasive but also finds applications in functional ceramics, refractories, abrasives, and metallurgical raw materials. With its remarkable properties such as stable chemistry, high thermal conductivity, low thermal expansion, and excellent wear resistance, it can be utilized for coating hydraulic turbine components and functioning as a high-grade refractory material.
