Thermal Conductivity of Double Continuous Disordered Solid Solutions

Thermal Conductivity of Disordered Continuous Ternary Solid Solutions of Semiconductor Compounds PbTe–PbSe–PbS

“…When combined with the results in [6] and ways of calculating the thermal conductivity of continuous binary solid solutions taken from the literature, our approach can be recommended for approximating (predicting) the thermal conductivity of continuous ternary solid solutions, along with generalizing, interpolating, extrapolating, and controlling the results from measurements in developing new alloys to reduce expenditures of time and money.…”

“…To describe the concentration dependence of the thermal conductivity of a ternary solid solution in sections with X i = const, we use concepts of a continuum of solution structure and the properties of its components in combination with successive reduction of the structure of a three-component nonuniform system to the structure of a two-component system [6], for which a way of determining the thermal conductivity is known.…”

“…If figurative point N corresponding to the solid solution composition falls in, e.g., the range of concentrations limited by the 1В2 triangle (Fig. 1), it is sufficient to know the thermal conductivity of the component В, the thermal conductivity of two solid solutions B-A and B-C [6], and the alloy's composition in order to calculate the thermal conductivity of all points on the thermal conductivity surface above this region.…”
