摘要：

ZrB(2)-SiC-B(4)C is sintered at 1700 degrees C by spark plasma sintering process. The effect of B(4)C content on the mechanical properties and microstructure of ZrB(2)-SiC based ceramics is studied. The results show that, with the content of B(4)C increases, the relative density and room-temperature strength decrease in the ZrB(2)-SiC-B(4)C composite. The fracture toughness rises at first and then falls down. The high temperature strength increases.
