Physical properties of liquid gadolinium (to a temperature of 4000 k) at pulse current heating of thin foil

Abstract

First the data were obtained for the enthalpy and heat capacity of liquid gadolinium with temperature measurement, ranging from 2000 K up to 4000 K. The heat capacity of gadolinium obtained under pulse current heating (5 μs), is consistent with the experimental data of stationary measurements near 2000 K (the magnitude of the heat capacity of liquid gadolinium equals ≈0.3 J/g-K for both cases). Above 3000 K, the heat capacity increases slightly, reaching values of 0.5 J/g-K for temperatures of 4000–4500 K (under a slightly elevated pressure).
