Abstract

The most reliable molar entropies of solid phases are calculated from low-temperature heat capacity values. In the case of alkaline earth metal molybdates these data had been measured until very recently only for MgMoO4(cr) and CaMoO4, powellite, at T > 50 K. Consequently extrapolation of the heat capacity function to T = 0 K played and still plays an important role. With state of the art mathematical routines integrals can be included in the nonlinear fit of experimental data leading to the adjustable parameters of analytical functions, e.g. \(C_{p\text{, m}}^{\text{o}} = F(T)\) and their uncertainties. This paper compares classical and recently developed methods to evaluate \(C_{p\text{, m}}^{\text{o}}\) data for SrMoO4, CaMoO4, and MgMoO4.
