(Zr1/3Nb1/3Ti1/3)C metal carbide solid-solution ceramic has been successfully fabricated by hot pressing sintering at 2473K using ZrC, NbC, and TiC powders as raw materials. The results show that the as-prepared solid-solution ceramic possesses a single rock-salt crystal structure of metal carbides and simultaneously exhibits high compositional uniformity from nanoscale to microscale. By taking advantage of these unique features, it shows relatively high hardness of 38.8 +/- 4.4Gpa and elastic modulus of 481.8 +/- 31.0Gpa and relatively low thermal conductivity of 17.1 +/- 0.3W/(mK) and thermal diffusivity of 6.1 +/- 0.1 mm(2)/s, which may attribute primarily to the presence of solid solution effects.
