Silicon Carbide Ceramic Gear Product Introduction
Silicon carbide ceramic (SiC) is an advanced ceramic material with silicon carbide as its main component, possessing the following significant characteristics:
1. High hardness: Mohs hardness reaches 9.2-9.6, second only to diamond and boron carbide, giving it excellent wear resistance. 2. High-temperature stability: High-temperature strength can be maintained up to 1600℃, making it one of the best high-temperature performing ceramic materials known.
3. Chemical stability: Resistant to strong acids and bases, performing excellently in harsh chemical environments.
4. Low friction coefficient: The surface friction coefficient is only 0.01-0.02, exhibiting self-lubricating properties.
5. High thermal conductivity: Thermal conductivity reaches 120-200 W/(m·K), enabling effective heat dissipation.
