Urusov’s crystal-energy theory of isomorphous substitutions is used to calculate mixing energies (interaction parameters) and critical decomposition temperatures (stability temperatures) of solid solutions in the Sc\(_{1-x}\)Ln\(_x\)AsO\(_4\) (Ln=Sm–Lu, Y) (I) and Tb\(_x\)Ln\(_{1-x}\)AsO\(_4\) (Ln=Y, Tm) (II) systems with zircon structure. Based on the obtained calculation results, for systems (I), a diagram is presented to estimate the stability regions of solid solutions and predict the substitution limits based on the temperature, or the decomposition temperature depending on the given substitution limits. They are characterized by the presence of regions of thermodynamical stability, instability, and metastability of solid solutions. In systems (II), solid solutions are thermodynamically stable above the critical temperatures and metastable below the critical temperatures. Within the limits of the method error, the calculation results for systems (II) do not contradict the experimental data described previously in the literature. The present results can be useful in choosing the ratio of components in ‘mixed’ matrices, the amount of activator in luminescent, laser and other practically important materials, as well as in matrices for immobilization of toxic and radioactive waste.

Keywords: solid solution, energy of mixing, isomorphous substitutions, orthoarsenates of rare-earth elements, scandium, terbium
