The electrical conductivity of complex oxides K1-xNaxSbWO6 (0≤x≤0.6) and K1-xLixSbWO6 (0≤ x≤0.4), which have a pyrochlore-type structure, was studied. The temperature dependence of the ion permeability of the compounds and the value of the ion radius were determined. As the ion radius value of the alkali metal decreases, the value of the activation energy decreases, and the ion permeability increases. A model of ion transport has been proposed in these compounds. It was found that the compound containing Li0.4K0.6SbWO6 reaches the maximum values of electrical conductivity.
