Silicon carbide honeycomb ceramics are honeycomb ceramics with silicon carbide (sic) as the main component.
Silicon carbide (sic) ceramic honeycomb not only has excellent mechanical properties at room temperature, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low coefficient of friction, but also high temperature mechanical properties (strength , creep resistance, etc.) are the best known ceramic materials. The high temperature strength of hot pressing sintering, pressureless sintering and hot isostatic pressing sintering can be maintained up to 1600°C, which is the best high temperature strength among ceramic materials. Oxidation resistance is also the best among all non-oxide ceramics. The disadvantage of silicon carbide (sic honeycomb) ceramics is that the fracture toughness is low, that is, the brittleness is relatively high. For this reason, in recent years, composite ceramics based on silicon carbide (sic) honeycomb ceramics, such as fiber (or whisker) reinforcement, Heterogeneous particle dispersion strengthening and functionally graded materials have emerged one after another, improving the toughness and strength of monomer materials. Silicon carbide (sic) honeycomb ceramics have been widely used in petroleum, chemical industry, microelectronics, automobile, aerospace, aviation, papermaking, laser, mining and atomic energy and other industrial fields.
Silicon carbide honeycomb ceramics is a new type of ceramic product with a honeycomb-like structure developed in the past year. From the earliest use in the exhaust gas purification of small cars to today, it is widely used in chemical industry, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries, and it is becoming more and more widespread, with considerable development prospects.
