The influence of high-energy mechanical activation on the thermoelectric properties of polycrystalline Dy0.075Sr0.925Ti1-xPxO3 (x=0, 0.01, 0.025) samples has been studied. The synthesized solid solutions have a negative Seebeck coefficient, increasing almost linearly in absolute value with increasing temperature. For all samples, a change in the type of electrical conductivity from semiconductor to metallic is observed. A comparative analysis of the results obtained in the temperature range of 300-800 K showed a significant decrease in electrical resistivity with a slight change in the Seebeck coefficient, increasing the thermoelectric power factor to 12.2 μW/(cm·K^2) at x=0. Despite the increase in thermal conductivity measured at temperature 300-673 K, thermoelectric figure of merit ZT of mechanically activated samples at T=670 K is higher than that of those not subjected to mechanical activation. The value of figure of merit ZT=0.31 obtained for x=0 is one of the highest reported in the literature for thermoelectrics based on SrTiO3 at this temperature. Replacing titanium with phosphorus does not improve thermoelectric characteristics. A tendency towards a decrease in electrical resistance and an increase in thermal conductivity as a result of mechanical activation is observed for all studied samples. Keywords: thermoelectricity, electron microscopy, mechanical activation, solid solutions.
