The purpose of the work – multi-parameter optimization of technology for preparation of thermoelectric materials based on Ві-Те for achieving extreme thermoelectric characteristics. Research methods – computer simulation of the process of growing thermoelectric materials based on Ві-Те, experimental methods for optimization of technological processes of their growing and measuring parameters on a specially developed equipment. The optimal composition of components of thermoelectric materials based on bismuth telluride of n- and p-type conductivity was determined and confirmed experimentally. Computer simulation and optimization of the process of growing such materials by vertical zone melting was made. Based on the research results, a technological process of manufacturing thermoelectric materials based on Bi-Te with extreme characteristics has been developed. These materials are optimized for space-purpose modules that exceed the world level in their characteristics. The results of the work have been introduced in the production of space-purpose cooling modules. It is advisable to continue the research in order to improve the mechanical properties of thermoelectric materials based on Bi-Te. Conditions for receiving the report: by agreement.
