As an important component of engineering and functional materials, advanced ceramic materials have broad application prospects in new energy, communication electronics, semiconductor, aerospace and other industrial fields. However, because most of the ceramic powders are ionic bond or covalent bond compounds, the traditional sintering process requires high sintering temperature and long holding time to prepare fully dense ceramics, which inevitably leads to grain coarsening and pore residue, thus affecting the properties of ceramic materials. In order to reduce sintering temperature and time, as well as improve the density and properties of ceramic materials， many novel sintering technologies have been developed, including spark plasma sintering (SPS), flash sintering (FS), cold sintering (CS) and oscillatory pressure sintering (OPS). By using the above sintering technology, the sintering temperature and sintering time of ceramic materials can be significantly reduced, and the properties of materials can be improved, so that the application scope of ceramic materials can be expanded. In this paper, the research progress of novel sintering technologies for advanced ceramics is reviewed from both theoretical and practical aspects. The technical advantages and application prospects of novel sintering technologies in the preparation of highperformance ceramics are described. It is expected that this paper can provide reference for the research, development and application of novel sintering technologies for advanced ceramics.
