Abstract:
The Er-Sn-Se system was studied by differential thermal analysis, X-ray powder diffraction, and microstructure examination and also by microhardness and density measurements. A congruent triangulation scheme and a liquidus surface projection were constructed. Fourteen primary crystallization fields, including those of the ternary compounds ErSnSe2, Er2SnSe4, Er2SnSe5, and Er2Sn3Se9, were found, and the types and coordinates of nonvariant and monovariant equilibria were determined.
