The results of study of thermoelectric properties of lead telluride obtained by method of powder pressing arepresented. A modified electrical model for interpreting the empirical dependences σ (T) is proposed, according towhich the compressed sample is represented by a system of crystallites with intergranular boundaries whoseproperties differ along and across the compression axis.
