Cuprous ion conductive glasses in the system (20-x) CuI-x CuBr-40 Cu₂O 40 P₂O₅ as well as (40-y) CuI-y CuBr-30 Cu2O-30 P₂O₅ were prepared. The glass formation was observed in the all range of substitution of CuI by CuBr. AII the prepared glasses show similar infrared spectra typical for metaphosphate glasses containing mainly chains of the (PO₃⁻) anions. The conductivity of glasses at room temperature σ₂₅ increases with an increase of total content of cuprous halides. The significant positive deviation of the conductivity from the additivity, by substitution of Br⁻ for I⁻ anions (mixed anion effect), has not been observed in the glasses under study. |
