Abstract: Advanced ceramic materials have unparalleled structural characteristics such as high hardness, high modulus, high temperature resistance, corrosion resistance, as well as excellent functional properties such as thermal, optical and electrical properties. Therefore, they have been increasingly applied in fields of aerospace, information technology, national defense and military industry, biomedicine, and new energy. The demand for high performance advanced ceramic materials has driven the development of preparation processes. The application of vacuum technology in ceramic forming and sintering technology can improve ceramic properties by influencing on the densification, the uniformity of composition, and the distribution of grain sizes. This study summarized the application of vacuum technology in various forming and sintering methods, and discussed the mechanism of the effects of vacuum atmosphere on improving ceramic properties. Finally, prospects are made for future research directions.

Key words: advanced ceramic, vacuum technology, forming, sintering
