Industrial use of boron carbide strength and toughness is lower, this is mainly due to the organization bulky defect density is not high, through the basic way of improving the sintering density fine grains can significantly improve the strength, but not fracture toughness increase, which is associated with the limitations of single phase material itself Thus, to reduce the boron carbide transgranular fracture tendency to increase the fracture toughness, go the way of compound seems to be the last choice a large number of studies have shown that the composite additive can greatly reduce the sintering temperature and pressure, under the condition of high temperature and high pressure, high density pure boron carbide ceramics, with excellent mechanical properties.
