▼Performance characteristic
1. Corrosion resistance : silicon carbide ceramic rings have good resistance to a variety of chemical media, and can work stably in corrosive environments such as acids, alkalis and organic solvents. It has high chemical stability and strong acid resistance, but relatively weak alkaline resistance
2. High temperature stability : silicon carbide ceramic ring at high temperature environment can maintain good mechanical properties and chemical stability, suitable for high temperature applications. It has excellent high temperature resistance and can maintain stable mechanical properties and chemical properties at temperatures up to 1400℃
3. Mechanical strength : silicon carbide ceramic ring has high hardness, Mohs hardness up to 9.5, bending strength up to 600-800 MPa, even at high temperatures can maintain a high level of strength. Its low coefficient of thermal expansion and high modulus of elasticity make it perform well under high pressure and impact force
4. Wear resistance : silicon carbide ceramic ring has excellent wear resistance, suitable for high-speed friction and wear environment. Its low coefficient of friction and excellent wear resistance reduce wear and increase service life
5. Thermal conductivity : silicon carbide ceramic ring has high thermal conductivity, which can effectively dissipate heat and prevent performance degradation caused by temperature increase. Its thermal conductivity is 80-120 W/(m·K) and is suitable for applications where good thermal conductivity is required
6. Electrical properties : The electrical properties of silicon carbide ceramics can be doped to achieve the transformation of insulation, semiconductor to conductor. The internal resistance of high purity silicon carbide decreases with the increase of temperature, and the conductivity of different impurities silicon carbide is also different |
