Abstract
FIELD: production of thermoelectric materials based on chalcogenides of antimony and / or bismuth used for direct transformation of electrical power into heat power in cooling apparatuses and aggregates for air conditioning, etc. SUBSTANCE: method provides for synthesis during heating of initial components till their melting in air-evacuated ampoule, following cooling and vertical zone recrystallization. Ampoule has variable cross-section with smaller diameter part. Synthesis is carried out using rotation of ampoule around its transversal axis. Cooling is exercised by hardening of melt placed in ampoule part with smaller diameter, that is then separated without depressurization. Zone recrystallization is exercised by high frequency currents under value of temperature gradient in zone of 150 - 210 C/cm. Initial components are preliminary purified. Output of good material is 80 %. For example, they produced alloy BiBiSbTe+ 1.5 mass % of Te, that has thermal electromotive force (emf) α = 238 mcV/deg. and thermoelectric durability Z = 3.45 10. EFFECT: increased productivity of process and improved electrical and mechanical features of material. 2 dwg, 2 tbl
