Description

The character of interaction in the systems Cu6PS5І - Cu7PS6(І), Cu6PS5Br - Cu7PS6(ІІ) have been investigated by DTA, XRD, microstructure analyses, T - x diagrams of former systems have been built. The system (I) set of boundary formation and system (II) - unlimited solid solution heterovalent anion-anion substitution. Single crystals of solid solutions Cu7-xPS6-xI(Br)x, were grown by the method of crystallization from the melt, electrochemical and physical investigations were carried. The composition of materials based on of Cu7-xPS6-xI(Br)x single crystals with optimal parameters for use as membrane of electrochemical sensors for copper-selective electrode was identified. The working range of concentrations, pH, selectivity, sensitivity limits, electrode potentials depending on the concentration, types of foreign ions for ionoselective electrodes have been established.
