Abstract
In this work we obtain and certify one-dimensional particles of the composition Bi2Te2.7Se0.3 of submicron size with an atypical growth direction. Further, the influence of the temperature of spark plasma sintering on the grain morphology and size, crystal-lattice parameters, elemental composition, and density of the samples obtained are investigated. The features of the formation of the crystallographic texture depending on the sintering temperature are also established. A temperature is revealed that allows for preservation of the crystal structure characteristic of the initial powder and materials with an atypical crystallographic texture to obtained. The thermoelectric properties of the materials obtained are also studied.
