AB  - The Ho-Bi-Te ternary system was studied by DTA, X-ray diffraction, and MSA, as well as 
by measuring microhardness and determining density, congruent triangulation scheme and 
projection of the liquidus surface, types and coordinates of mono- and invariant equilibria. 
It is established that this system is triangulated into five pseudo-ternary systems. It was 
discovered that an incongruently melting ternary compound containing HoBiTe<sub>3</sub> is formed 
in the Ho-Bi-Te ternary system. X-ray phase analysis established that the HoBiTe<sub>3</sub> 
compound crystallises in a tetragonal system with lattice parameters: a = 19.99, с = 13.82 
Å, Z = 3. Studying the nature of the interaction of the components of the quasi-binary section 
Bi<sub>2</sub>Te<sub>3</sub>-Ho<sub>2</sub>Te<sub>3</sub> of the Ho-Bi-Te ternary system, as well as thermoelectric materials formed 
by combining Bi<sub>2</sub>Te<sub>3</sub> with rare-earth tellurides, is of interest from a scientific and practical 
point of view.
