Silicon carbide ceramics element are ceramic materials second only to diamonds in advanced ceramics, and have excellent wear resistance and heat dissipation.SiC can remain stable and non-deformed under a wide range of temperatures and maintain reliability in harsh environments. It is suitable for the production of various complex parts, such as silicon carbide ceramic heating elements, sic bearings, sic mechanical seals, etc.
SiC Ceramics Element Advantages
- Vickers hardness ≥20GPa
- Oxidation resistance, making it wear-resistant
- Operating temperature up to 1600°C
- Good corrosion resistance
- Resistant to thermal shock (ΔT = 1,100 K)
- High-temperature mechanical properties are the best among known ceramic materials
