The thermal diffusivities of BaTiO3 materials are measured by phototh ermal technique at different pressures, sintering temperatures and tantalum dopi ng quantities. The effect of tantalum doping on thermal conduction of BaTiO3 materials is studied in this paper. When tantalum doping quantity is l ess than 1.5mol%, the diffusivity of BaTiO3 increase with the incre ase of the tantalum doping. When tantalum doping quantity is greater than 1.5mol %, the diffusivity of BaTiO3 decreases with the increase of the tan talum doping. The experimental results of doped BaTiO3 materials are analyzed and discussed.
