silicon carbide ceramic ring

Introduction to the characteristics of silicon carbide ceramic rings

Silicon carbide ceramic rings not only have excellent room temperature mechanical properties, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also high temperature mechanical properties (strength, creep resistance Denaturation, etc.) is the best among known ceramic materials.

Silicon carbide ceramics have excellent mechanical properties, excellent oxidation resistance, high wear resistance and low friction coefficient. The biggest feature of silicon carbide ceramics is high high temperature strength. The strength of ordinary ceramic materials will be significantly reduced at 1200 ~ 1400 degrees Celsius, while the flexural strength of silicon carbide still maintains a high level of 500 ~ 600MPa at 1400 degrees Celsius, so its work The temperature can reach 1600 ~ 1700 degrees Celsius. In addition, silicon carbide ceramics have high thermal conductivity, second only to beryllium oxide ceramics among ceramics.
