For high performance characteristics of thermoelements and economic feasibility of their use, it is necessary to obtain material with high values ??of the Seebeck coefficient, specific conductivity and as low as possible thermal conductivity. However, the improvement of one of these parameters often causes deterioration of another, which complicates the optimization of the properties of the thermoelectric material as a whole. The problem was solved by introducing high-melting particles (ZnO, CdTe, TiO2) into the crystal matrix of PbTe, which significantly reduce the thermal conductivity of the material without significantly affecting its other characteristics. As a result, the thermal conductivity of the material was reduced by a factor of 2, which, with constant values ??of electrical conductivity and the Seebeck coefficient, would increase thermoelectric quality factor as many times as possible.  Product Description popup.authors popup.nrat_date 2020-04-02 Close
