Аннотация:Optimum compositions of ion-selective membranes in quasi-binary systems CuCl-CdCl2, LiCl-CdCl2, and ln(2)S(3)-InCl3 are selected by a method of coulometric titration in cells with solid electrolytes. Transport numbers for ions are close to unity for the optimum compositions; transport numbers for electrons are vanishingly small ((t) over bar (e) < 10(-3) to 10(-4)); the electroconductivity is equal to approximate to 10(-3) S cm(-1) at 200 degrees C; the diffusion coefficients for the current-producing component are on the order of 10(-6) to 10(-7) cm(2) s(-1). When using a solid electrolyte of the composition CuCl-CdCl2, which contains 30 mol % CdCl2, methods of emf and electroconduction reveal that the region of homogeneity of copper(I) selenide falls in the region of compositions CU1.33Se-Cu2.67Se.
