Abstract
The ionic conductivity is calculated for a solid in which the ions are undergoing an order-disorder phase transition. The interacting ion system is described by a lattice gas with a weak hopping term. Exact results are obtained in one and two dimensions by using the exact results known for the Ising model. The calculated theoretical conductivity agrees very well with the temperature dependence found experimentally.Keywords
