abstract = {Using ab initio quantum chemistry we computed the excess
thermodynamic properties and the elastic moduli for a series
of monazite-type single substitution solid solutions
(Ln1−xLnxPO4). We found that the Margules interaction
parameters of all the solid solutions can be described by a
simple function of the endmembers volume mismatch ΔV , i.e.
W(kJ/mol)=0.616(ΔV(cm3/mol))2W(kJ/mol)=0.616(ΔV(cm3/mol))2.
We show that the obtained relationship could be also derived
by considering the strain energy resulting from the
substitution of cations of different sizes, knowing the
Young's modulus and the volumes of endmembers. This
indicates that the strain resulting from the structural
incorporation of cations is a major factor responsible for
arising of the excess properties in monazite-type ceramics.
Our results show thus a way to estimate the excess
thermodynamic properties of solid solutions from the
structural and elastic parameters, namely the endmembers
volumes and the Young's modulus, which could be easily
measured or computed.},
