Electrical properties of triple molybdates Rb5LnHf(MoO4)6

Triple molybdates of the compositions Rb(5)LnHf(MoO4)(6) (5:1:2) and Rb(2)LnHf(2)(MoO4)(6.5) (2:1:4), Ln = Ce-Lu, were prepared by solid-phase reactions. The temperature dependence of the electrical conductivity of the compounds Rb(5)LnHf(MoO4)(6) (5:1:2) at 200-500A degrees C was studied.
