摘要：
Empirical calculational approaches have been used to evaluate the enthalpy, entropy, heat capacity, and melting point of iron(II) niobate and iron(II) tantalate and the coefficients A, B, and C in an equation for the temperature dependence of their heat capacity. The melting point of FeTa2O6 has been experimentally determined to be 1891 ± 5 K. The calculated heat capacity (C°p (298.15 K)) of iron tantalate and the Gibbs energies of formation of FeN2O6 and FeTa2O6 have been compared to previously reported data.
