sintering mechanism and research progress of solid phase sintering of silicon carbide ceramics

Silicon carbide ceramics possess high performances such as high hardness and strength, oxidation and high temperature resistance, high thermal conductivity and low thermal expansion coefficient. Meanwhile, silicon carbide ceramics have excellent chemical stability as well as good corrosion resistance to most kinds of acid and base solutions. With performances given above, silicon carbide ceramics are widely used in petroleum, chemical industry, building materials, aviation, machinery and many other fields. This article mainly expounds the sintering mechanism of solid phase sintering of silicon carbide ceramics, and the domestic and abroad research progress in solid phase sintering of silicon carbide ceramics are expounded.
