Abstract  

The state diagrams (T-x) of the systems Ag2Te-ZnTe(I) and Ag2Te-Zn(II) are offered on the ground of data obtained by differential thermal analysis, X-ray phase analysis, microstructural analysis and measurements of the density and the microhardness of samples synthesized. The systems studied are quasibinary sections of the ternary system Ag-Zn-Te. System I is characterized by two eutectic and three eutectoidal non-variant equilibria as well as by an intermediate compound Ag2ZnTe2, which melts congruently at 880C. The latter exists in the range from 120 to 880C in two polymorphic modifications (Tʅ→β=515C). System II is characterized by one eutectic, two eutectoidal and one peritectic nonvariant equilibria, boundary solid solutions on the ground of Ag2Te and Zn and one intermediate phase of the composition Ag4Zn3Te2, which melts congruently at 880C.
