✦ Synopsis

The electrical conductivity and the transference number of silver-dissolved a-CuI in the superionic phase were measured as a function of temperature and composition. It was recognized that both Ag and Cu ions could be mobile and the activation energy for Ag ions is smaller than that for Cu ions. It is emphasized that the size of the Ag ion is more suitable for conduction than that of the Cu ion in this phase. Since the ionic radius for the Ag ion is larger than that of the Cu ion, we propose a model other than the gate model to explain this experimental fact.
