Samples with the composition, 0.7(AgI0.75AgCl0.25)-0.3[xAg2O-(1-x)B2O3], were prepared in which the host salt was a so-called quenched (AgI0.75AgCl0.25) mixed system instead of the usual AgI. They were made by dropping molten (650C) material into a 10C bath, by leaving 650C material to cool in a silica ampoule, or by furnace cooling from 650C to room temperature over 24h. The highest room-temperature conductivity (0.0223S/cm) was found for a composition with x = 0.833 that had been prepared by using the first (quenching) method.
