Abstract
The chemical interactions in the Bi2Te3-Ho2Te3 system are investigated by methods of physicochemical analysis (DTA, XRD, MSA, microhardness measurements and density determination), a state diagram is constructed. As a result, it was revealed that the system state diagram is a quasi-binary eutectic type. In the Bi2Te3Ho2Te3 system, in a 1: 1 ratio of components, one ternary compound of the HoBiTe3 composition, incongruently melting at 610°C, is formed. According to the results of X-ray phase analysis, it was found that the HoBiTe3 compound crystallizes in the tetragonal system with lattice parameters: a = 19.99; c = 13.82 Å, Z = 3, density ρpikn. = 7.30 g/cm3 ρrent. = 7.35 g/cm3.On the basis of the initial components, regions of solid solutions were found, which on the basis of Bi2Te3 reach 5 mol % Ho2Te3, and on the basis of Ho2Te3 -3 mol % Bi2Te3. Compounds Bi2Te3 and Ho2Te3 form a eutectic with a composition of 20 mol % Ho2Te3 and a temperature of 465°C.
