Zirconium carbide which is a kind of ultra high temperature ceramics has broad application prospects in the aerospace, nuclear technology, electronics and other fields. In order to improve the sintering properties and mechanical properties of ZrC ceramics, using ZrO2 powder and TaO2 powder as raw materials, TaC and ZrC solid solution powder were prepared by carbon thermal reduction, and the hot pressing sintering process was used to prepare ZrC-TaC ceramics. The effect of the sintering temperature on the solid solution behavior, densification behavior, tissue structure and mechanical properties was studied. The results show that the TaC in ZrC solid solubility is enhanced when the temperature is increased from 2000 ℃ to 2050 ℃.When TaC content is increased from 5% to 15%, the density of the composite, vickers hardness, fracture toughness and elastic modulus are decreased monotonously, and the bending strength has no apparent rule.
