Фазові рівноваги у системах на основі сполук Me2TeBr6, (Me – K,Rb,Cs)

Abstract

Using differential thermal analysis (DTA) and X-ray powder diffraction technique (XRD), phase equilibria of the systems based on the compounds Me2TeBr6 (Me – K, Rb, Cs) have been studied, and the proper temperature-composition diagram of these systems have been mapped. Phase diagrams of the systems K2TeBr6–Rb2TeBr6 and K2TeBr6–Cs2TeBr6 have been considerably revised. Physico-chemical interaction in the investigated systems K2TeBr6–Rb2TeBr6, K2TeBr6–Cs2TeBr6 and Rb2TeBr6–Cs2TeBr6 has been explained using the crystal chemistry fundamentals.
