A multicomponent (TiZrHfNbTaMo)C ceramic has been fabricated by pressureless sintering at temperatures from 2100 °C to 2500 °C, using an equimolar multicomponent carbide powder synthesized by carbothermal reduction as the starting material. Influence of sintering temperature on densification, microstructure and mechanical properties of the ceramics was investigated. The relative density increases with increasing sintering temperature, and a nearly fully dense sample is achieved by pressureless sintering at 2500 °C. Average grain size increases from 3.7 to 15.2 μm with increasing sintering temperature from 2300 to 2500 °C. The (TiZrHfNbTaMo)C ceramic sintered at 2400 °C exhibits a single phase fcc structure with homogeneous chemical composition, an average grain size of 7.0 μm and a relative density of 96.5%, while its measured hardness is 33.2 GPa at 100 mN and 23.2 GPa at 9.8 N.

以碳热还原法合成的等摩尔多组分碳化物粉末为原料，通过在2100°C至2500°C的温度下进行无压烧结，制备了多组分（TiZrHfNbTaMo）C陶瓷。研究了烧结温度对陶瓷致密化，组织和力学性能的影响。相对密度随烧结温度的升高而增加，并且通过在2500°C下进行无压烧结可获得几乎完全致密的样品。随着烧结温度从2300升高到2500°C，平均晶粒尺寸从3.7增加到15.2μm。在2400°C烧结的（TiZrHfNbTaMo）C陶瓷表现出具有均匀化学成分的单相fcc结构，平均晶粒尺寸为7.0μm，相对密度为96.5％，而其测得的硬度为33。
