What is silicon carbide ceramics
What is silicon carbide ceramics SiC ceramics 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 etc.) is the best among known ceramic materials. The high-temperature strength of hot-pressed sintering, pressureless sintering, and hot isostatic pressing sintered materials can be maintained up to 1600°C, making them the materials with the best high-temperature strength among ceramic materials. Oxidation resistance is also the best among all non-oxide ceramics. Also known as emery. Ceramics with silicon carbide SiC as the main component. The disadvantage of SiC ceramics is low fracture toughness, that is, high brittleness. For this reason, in recent years, SiC ceramic-based complex ceramics have been developed, such as fiber (or whisker) reinforcement, heterogeneous particle dispersion strengthening, and gradient functional materials. Appeared one after another, improving the toughness and strength of single materials. SiC ceramics have been widely used in industrial fields such as petroleum, chemical industry, microelectronics, automobile, aerospace, aviation, papermaking, laser, mining and atomic energy.
