The structure and conductivity of the fast oxide ion conducting system, Bi2ZnxV1-xO5.5-3x/2, where x was between 0.05 and 0.27, were investigated by using X-ray powder diffraction methods and alternating-current impedance spectroscopy. It was found that there was a compositional dependence of the conductivity as a function of temperature. This behaviour was related to the stabilization of various polymorphs within the system. The composition with x = 0.10 was found to exhibit a conductivity of 0.00409S/cm at 300K.
