Electric properties of tungstates with imperfect scheelite structure, Ln2(WO4)3 (Ln = La, Sm, Eu), are studied; the charge carrier type is determined in these phases. It is found that the conductivity type of Ln2(WO4)3 is predominantly ionic, though there is a contribution of n-type electron conductivity component in the case of Eu2(WO4)3. The Tubandt method was used to establish a negligible contribution of the [WO4]2– anion into transport, which, together with the results of the EMF technique, points to the predominantly oxygen character of conductivity.
