The object of study of this work is a powder thermoelectric material systems Bi-Sb-Te, Bi-Se-Te obtained by spark plasma sintering. The aim is to improve the efficiency of bulk thermoelectric materials, through the creation of crystalline and amorphous structures with low values ??of thermal conductivity and controlled microstructure for high-performance thermoelectric energy converters that will ensure the growth of competitiveness of domestic thermoelectric products in the international market. The goal also includes the development of methods of optimization of powder nanostructures to achieve maximum values ??of merit by spark plasma sintering. To achieve the goal of computer simulation techniques used by the spark plasma sintering process (SPS) in relation to the powders of the thermoelectric materials based on bismuth telluride. Within the framework of different model approaches identified ways to reduce the thermal conductivity for powder patterns of thermoelectric material. The optimal size of the powder for the SPS methods for producing thermoelectric materials with high quality factor. Equipment has been developed to produce high-performance SPS method of thermoelectric materials. Experimental study of the effect powder structure, technological regimes, the raw material parameters on the quality factor of SPS thermoelectric materials. The methods of precise measurements of SPS sample materials. Experiments proved that the method can improve SPS termoefektivnist material in 1.5 times in comparison with the best single-crystal materials.THERMOELECTRIC MATERIALS, THERMOELECTRIC GOOD QUALITY, SPARK PLASMA SINTERING.
