Simulations were made of superionic ternary compounds with the composition, AgxCu1-xI for x = 0.0, 0.25, 0.5, 0.75 or 1.0, using pair interatomic potentials of the form proposed by Vashishta and Rahman (1978) for metal iodides, and isothermal-isobaric ensembles. The diffusion coefficients of the cations were deduced from the mean square displacement versus time relationship. The activation energies were also estimated.
