Cuprous ion conduction in oxyhalide glasses of the system CuBr-Cu [sub 2] MoO [sub 4]-Cu [sub 3] PO [sub 4]

Abstract

This paper reports on cuprous ion-conducting glasses, prepared in the pseudo-ternary system CuBr-Cu[sub 2]MoO[sub 4]-Cu[sub 3]PO[sub 4]. These glasses exhibited high ionic conductivities in the range of 10[sup 0] to 10[sup [minus] 3] SM[sup [minus] 1] at room temperature. The infrared spectra showed that these glasses were composed of Cu[sup +], Br[sup [minus]], monomer MoO[sup 2[minus]][sub 4], and monomer PO[sup 3[minus]][sub 4] ions, and were classified as ionic glasses containing one type of cations and three different types of anions. The conductivity of these glasses increased with an increase in the amount of Cu[sup +] ions associated with the CuBr component. Substitution of PO[sup 3[minus]][sub 4] anions for MoO[sup 2[minus]][sub 4] anions caused a decrease in the conductivity of the glasses containing a given CuBr content.
