Abstract
Thermal diffusivity of polycrystalline tantalum at the temperatures range from 293 to 1800 K has been measured by the laser flash method with the error of 2−4 %. Thermal conductivity has been calculated with the use of reference data on density and heat capacity. Approximating equations and tables of reference data for the temperature dependence of heat transfer coefficients have been obtained; comparison with the published data has been carried out.
