The pyknosis method of activated sintering of boron carbide ceramics was presented through some aspects of no-voltage sintering, adding to sintering assistant, forcing while sintering of pure boron carbide. The properties of boron carbide ceramics which were prepared at different sintering both at home and abroad were summarized. The mechanism of improving density of boron carbide ceramics through various methods was analysed. The merits and faults of various sintering methods were compared, the result indicates that it can improve density of boron carbide ceramics by synthesizing various measures.
