Abstract
The thermal diffusivity and the thermal conductivity of solid erbium in the temperature interval of 295-1475 K have been measured using the laser flash method. Approximation equations and a table of reference values for the temperature dependence of heat transfer coefficients of the studied metal have been received. The obtained results have been compared with the known literature data. The temperature dependence of the erbium thermal conductivity is shown to be mainly determined by the electronic contribution.
