The work carried out a study of the effect of heat treatment on the mechanical strength and thermoelectric figure of merit of the Bi0.5Sb1.5Te3 solid solution. A decrease in the ultimate strength and the appearance of yield after annealing associated with antistructural defects were revealed. It has been established that heat treatment reduces the conductivity and thermal conductivity of the thermoelectric material, and also increases the Seebeck coefficient, which leads to an increase in thermoelectric efficiency from Bi0.5Sb1.5Te3 to 3.5· 10-3K-1. Keywords: Thermoelectricity, extrusion, solid solutions, density, quality factor, annealing.
