Product Introduction – What is Silicon Carbide (SiC)?
Silicon carbide (SiC) is a hard, chemically stable compound composed of silicon and carbon. Known for its extreme hardness, high thermal conductivity, and excellent resistance to chemical corrosion, SiC is widely used in industrial applications including steelmaking, refractory materials, abrasives, ceramics, and electronics.
Key Features of Silicon Carbide:
High Hardness: SiC ranks close to diamond on the Mohs scale, making it ideal for abrasive and cutting applications.
Excellent Thermal Resistance: Can withstand temperatures above 1600°C, suitable for furnaces, kilns, and high-temperature industrial processes.
Chemical Stability: Resistant to oxidation, acids, and molten metals, ensuring long-term performance in harsh environments.
Electrical Properties: Green SiC is a semiconductor, used in electronics and high-performance ceramic components.
Customizable Forms: Available as powder, grit, or blocks, with variable grades (88%, 90%) and colors (black or green).
Industrial Significance:
Steelmaking: Acts as a deoxidizer and alloying agent, improving steel quality and efficiency.
Refractory Materials: Enhances thermal stability and wear resistance of furnace linings.
Abrasives: High hardness makes it suitable for polishing, grinding, and cutting tools.
Advanced Ceramics & Electronics: Micro and nano powders are used in LEDs, semiconductors, and precision ceramic components.
