description: In the theoretical part, a literature review is written on thermoelectricity, thermoelectric materials, the structure of bismuth telluride, state diagrams of bismuth telluride and its compounds, methods for their preparation and reflection spectra. The aim of this work is to study the Raman spectra of industrial samples based on bismuth telluride, manufactured by extrusion and zone melting, for greater measurement accuracy, compared with x-ray studies. The experimental part consisted of studies of X-ray and Raman spectra of these samples. In the X-ray study for the extruded sample, electron-microscopic and X-ray phase analyzes were carried out, as well as X-ray diffraction patterns of different parts of the ingots rotated in the holder plane were taken. It was found that the sample made by extrusion has a texture. The analysis of X-ray and Raman spectra for the extruded sample showed a constant chemical composition in combination with a slight anisotropy, which correlates with previously obtained results. For the industrial sample obtained by the zone melting method, only the Raman spectrum was constructed, since these samples have a random heterogeneity in the distribution of the composition.
