Data for: Approximation of thermodynamic properties of potassium and some binary compounds by Einstein functions sum including temperatures below 5 K

This dataset contains input isobaric heat capacity and heat content data, assigned statistical weights, optimized parameters of thermodynamic models for solid potassium K, lead iodide PbI2, thorium sulphide ThS, thorium disulphide ThS2, uranium diboride UB2 and triuranium silicide U3Si. The models are based on the weighted sums of Einstein (Einstein-Planck) functions. It also contains tabulated values of standard thermodynamic functions for these compounds.
