The experimental data for the dielectric response of certain ionically cond
ucting ceramics obtained by Kuhn and coworkers were re-interpreted using th
e "universal" dielectric formalism and the results reveal the presence of t
wo well defined processes with power law exponents of - 0.6 to - 0.7 for th
e high-temperature, low-frequency branch and - 0.3 and less for the low-tem
perature, high-frequency branch. The physical significance of these results
is discussed in terms of transport in strongly anisotropic materials. (C)
