Аннотация:We propose a mathematical model to fit the temperature-dependent thermal conductivity of M1−xRxF2+x heterovalent solid solutions where M stands for alkaline-earth metals and R for rare-earth metals. These solid solutions experience composition-driven transition from the crystal-like to glass-like behavior of thermal conductivity. When tested on Ca1−xYbxF2+x solid solutions, the model showed a potential for use with an option for further improvements.
