Product Introduction of Silicon Carbide Ceramic Insulation Boards:
Silicon carbide ceramic insulation boards are high-performance ceramic materials based on silicon carbide (SiC). Their manufacturing process involves the formation of a dense silicon carbide structure through complex chemical reactions between high-purity carbon and silicon. This material possesses the following significant characteristics:
1. High hardness: With a Mohs hardness of approximately 9.5, close to that of diamond, it is suitable for high-wear environments.
2. High temperature resistance: It has a melting point of up to 2700℃ and can operate stably for extended periods at 1600℃, and withstand temperatures above 2000℃ for short periods.
3. High thermal conductivity: The thermal conductivity reaches 120-270 W/m·K, significantly superior to traditional ceramic materials.
4. Chemical stability: It exhibits excellent corrosion resistance to strong acids, strong bases, and corrosive gases.
5. Oxidation resistance: An oxide film forms on the surface under high-temperature conditions, effectively preventing further oxidation.
