In this study, high temperature thermal properties of hot pressing sintered TiB
2 ceramics was investigated in order to determine the feasibility to the divertor plate of fusion materials. The thermal expansion coefficient was 8.2×10
-6/K in a range of room temperature to 1073K. The thermal diffusivity and specific heat were measured by the laser flash method. The thermal diffusivity and specific heat increased with increasing temperature. The thermal conductivity was 57 to 75W/mK at temperatures from room temperature to 1273K.
