Abstract

Electrical transport in orthorhombic ytterbium and lutetium tungstates with Sc2(WO4)3 structural type was studied. It was proved by using two independent methods (EMF, dependence of conductivity on pressure of oxygen in the gas phase) that these phases are purely ionic conductors. It was found by Tubandt method for Lu2(WO4)3 the negligible contribution of the [WO4]2– anion into transport, which, together with the results of the EMF technique, indicates a predominantly oxygen character of conductivity.
