摘要

The thermal conductivity and thermal diffusivity of europium (Eu) in the solid and liquid states, including the melting-crystallization region, have been measured for the first time by the laser flash method in the temperature range from 298 to 1625 K. The error of measurement of the heat transfer coefficients was 4-6%. The data for the temperature regions of 298-550 K and 965-1625 K were obtained for the first time. Fitting equations and reference data for the temperature dependence of the thermal conductivity and thermal diffusivity of the metal have been received.
