For creation of thermo-electric devices of line (effect of Zeebek) and (effect of Pel't'e) back-action more frequent all utillized chalcogenides of lead (PbTe) and germanium (GeSe). Basic technological researches are directed on receipts high-homogeneous for chemical composition and the homogeneously alloyed compounds. It is attained in two ways: by optimization of temperature-sentinel terms of synthesis of compounds and them by the forced interfusion in the specially constructed technological devices [1,2]. One of basic parameters of these connections there are numerical values of coefficient of thermo-emf, which approach the level of developments of leading scientific centers and resulted at tables. Synthesized PbTe and GeSe compounds mechanically ground down to the powder-like state, sifted through sieves with the different sizes of openings (from 0,6 to 1,0) mm. From sifted factions weighed for made the branches of thermo-couples, creating the press 0,5 grammes of material, loaded in a press-form and of loading to 104 A and maintained in the tense state during 5 minutes. The surface of standards was covered the layer of copper (n-type) or nickel (р-type) for the best forming of electric contacts. Thermo-electric transformers assembled on linings. Made the thermo-electric modules which consisted of 4th consistently united a similar rank elements. At the temperature difference to 200 K coefficients of thermo-emf are: 460 mkV/K in PbTe and 540 mkV/K in GeSe thermoelements.
