- The thermal diffusivity and the electric resistivity of polycrystalline zinc have been measured as functions of temperature between 90 and 480 K at atmospheric pressure, and as functions of pressure up to 2 GPa (20 kbar) at room temperature. The pressure and temperature dependence of the thermal conductivity has been calculated by using literature data for the specific heat capacity. No minimum was found in the thermal conductivity at low temperatures. The pressure coefficient of the thermal conductivity was found to be 4.1 x 10-2 /GPa, which indicates that the Lorenz function of zinc decreases with increasing pressure.
