Abstract
The investigation of structural and electrical properties of pure alpha, beta and gamma bismuth molybdate phases is described and discussed. All phases undergo a slight structural change resulting in a decrease of conductivity due to an order-disorder change in the oxygen arrangement during the heating of samples. The changes observed in the electrical conductivities are reversible in the high-temperature regions and irreversible in the low-temperature ones. The blocking of oxygen ion transport by the bismuth lone-pair electrons results in an increase of the activation energy and a decrease of the electrical conductivity in the high-temperature region. Relatively high relative dielectric permittivities epsilon(r), 36-52, were observed depending on the investigated phase.
