The temperature-concentration dependence of electrical conductivity was stu
died in glasses of the systems Ba(PO3)(2)-Ba(Hal)(2), where Hal = Cl, Br, I
. The Hittorf method was applied to find the transport numbers for chloride
, bromide, and iodide ions and their concentration dependence was determine
d. The effect of halide ions on the structure of glasses is demonstrated by
IR spectroscopic studies.
