The factors influencing the value of the thermal conductivity coefficient of thermoelectric materials based onlead telluride obtained by powder pressing method have been analyzed. The model is presented and itsparameters are defined, which explains qualitatively and quantitatively the temperature dependences of thethermal conductivity coefficient of PbTe and PbSnAgTe.
