The three-phase ceramic powders of Ti₂AlC, TiB2 and TiC are synthesized by self-propagating high-temperature synthesis(SHS) technology. Ti₂AlC/TiB₂/TiC block multiphase ceramics are prepared by spark plasma sintering(SPS) method. The results show that Ti₂AlC is the matrix phase, and TiB₂ , TiC are dispersed on the matrix. The high density of Ti₂AlC/TiB₂/TiC block multiphase ceramic is 99.6%, the average microhardness value is 12.96 GPa, the fracture toughness value is 45.28 MPa·m1/2.
