Glass formation and ion conduction in the CuCl–Cu2MoO4–Cu3PO4 system
Abstract
Copper(I) ion-conducting glasses have been obtained over a wide composition range in the system CuCl–Cu2MoO4–Cu3PO4 as an island in the composition triangle, although the glass-forming region of the CuCl-containing system was narrower than those of the systems CuBr–Cu2MoO4–Cu3PO4 and Cul–Cu2MoO4–Cu3PO4. Infrared spectra showed that those glasses were composed of Cu+ ions, halide ions, X–(X = Cl, Br, I), ortho-molybdate anions MoO2–4 and orthophosphate anions PO3–4 only, as expected from their chemical composition. The conductivities of the CuCl-containing glasses were in the range 100–10–4S m–1 at room temperature, and these high ion conductivities were nearly the same (very slightly lower) as those of the Cul-and CuBr-containing glasses with analogous compositions.
