Abstract

The glass-forming region in the ternary system CuI-Cu2O-P2O5, from which Cu2+ ion formation has been excluded, is described and compared with that in the corresponding Ag+-based system. The glasses are characterized by Tg values some 50°C higher than in the silver systems. Frequency independent (dc) conductivities along the join CuI+CuPO3 have been determined over a wide range, and found to be characterized by both higher activation energies and pre-exponential constants than the silv{approaches the limit}r glasses. The combination leads to higher conductivities in the Cu+-based glasses in the composition range 20-30 mole% CuI at room temperature and above.
