A brief summery is given on the research progress in liquid-phase sintering（LPS） of SiC about the sintering additives, sintering techniques and sintering mechanism. Some new sintering methods are introduced and the microstructure and properties of LPS-SiC are discussed. SiC-YAG and SiC-AI-B-C sintering systems are discussed focusing on their characteristics and composite properties. The sintering mechanism and development of SPS and microwave sintering of SiC ceramics are introduced.
