Abstract: | A review is given of the results of calculations of the heat capacity C(T) of solid tantalum in a wide temperature range from helium temperatures to the melting point of metal T-m. Calculation of the heat capacity of the metal within the framework of a self-consistent thermodynamic model (SCTDM) of a solid body versus the experimental (reference) data on C(T) is performed. In the range from the Debye temperature theta(0) similar to 250 K to the beginning of the premelting region T similar to 0.8T(m), the standard SCTDM ensured an adequate description of the tantalum heat capacity with a mean square error of less than 0.5 J K-1 mol(-1). At lower and higher temperatures, extra models are needed. A number of thermodynamic characteristics of the element are determined whose values were previously absent or needed verification. |
