Abstract :
Profiled (Bi0.25Sb0.75)2Te3-polycrystals in the form of flat plates were grown by directed crystallization method. Microstructure peculiarities of crystals were studied. It was shown that heat treatments at 300-600°C-temperature range led to some changes in the state of tellurium-enriched phase. These changes were explained by the character of Bi-Sb-Te phase diagram near to (Bi0.25Sb0.75)2Te3 compositions.
