Тензиметричні дослідження сполук Cd2As3Br та Cd2As3I

Abstract

The temperature dependence of saturated pressure of Cadmium Arsenidobromide and Cadmium Arsenidoiodide has been investigated. Due to shifting of the composition from the homogeneity region, lgP – 1/T in the temperature interval of 649-967 K for Cd2As3Br(I) are observed both as fractures and as pressure jump on the dependences. Mass-spectra of ternary phases demonstrate incongruent character of the compounds evaporation. On the basis of tensimetric investigations, the optimal single crystal growing conditions of the compounds are determined.
