(1) Research on basic technology of special ceramics, such as sintering mechanism, detection technology and powder preparation technology; (2) Research on superconducting ceramics; (3) Thin film or amorphization of special ceramics is an effective method to improve the function of ceramics, so many countries have studied it as a main content; (4) Fibrosis of ceramics is an important foundation for the development of thermal insulation materials and composite reinforcement materials. At present, foreign countries, especially Japan, attach great importance to the research of ceramic fibers and whisker-reinforced metal composite materials. The research focuses on silicon carbide and Silicon nitride (5) Porous ceramics have attracted attention from all walks of life because of their special structure; (6) The problem of ceramics and ceramics or ceramics combined with other materials (ceramic fiber reinforced ceramics, ceramic fiber reinforced metals) is also the focus of research at this stage; (7) Among non-nitride ceramics, the most studied abroad are ceramic engines, high-pressure heat exchangers and ceramic tools; (8) With the development of new disciplines such as biochemistry and biomedicine, the development of bioceramics has become more and more important.
