SYNTHESIS AND PHYSICO-CHEMICAL STUDY OF THE Bi2Te3-HoTe3 SYSTEM
Abstract
The physicochemical study of the Bi2Te3-HoTe3 system was carried out by differential thermal (DTA), X-ray phase (XRD), microstructural (MSA) methods, as well as by measuring the microhardness and determining the density, and a T-x phase diagram was constructed. It was found that the Bi2Te3-HoTe3 system is a partially quasibinary section of the Bi-Ho-Te ternary system. The system is undergoing eutectic equilibrium and peritectic transformation. Solid solutions based on Bi2Te3 at room temperature reach 6 mol % HoTe3, while solid solutions based on HoTe3 have practically not been established.
