Tantalum carbide materials were prepared by liquid precursor conversion, and the phase compositions and the microscopic structures of samples were characterized by XRD and SEM, respectively. Ta2O5 crystals are formed inside samples by 900℃ treatment, and after 1600～2000℃ high temperature treatment, the samples can almost be converted into tantalum carbide materials whose particles disperse homogeneously throughout the carbon matrix. As temperatures elevate, the graphitization degree of matrix increases and the grain size of tantalum carbide obviously enlarges, all of these are in favor of improving the anti-ablation properties of materials.
