Sadyk M. Luguev, Nataliya V. Lugueva, and Vladimir V. Sokolov
The thermal conductivity of NaLaS2-CaS system solid solutions has been experimentally investigated in the temperature range 80–450 K. It is determined the heat transfer mechanisms in the studied system. In all of the solid solutions studied, lattice thermal conductivity prevails. The composition dependence of thermal conductivity coefficient has been determined within the range of studied system. The pattern of thermal conductivity change under composition change is caused by defect structure of NaLaS2-CaS system solid solutions.
