Abstract: Ceramics based bismuth vanadate are conductors of oxygen ions and they are used as solid electrolytes in pressure sensors and fuel cells. The g-phase of Bi4V2O11 can be stabilized at T0 by partial substitution of V5+ ion by Cu2+ and Zn2+ ions to provide high electrical conductivity values between 100 and 400oC.
Polycrystalline samples of Bi4V1.8Cu0.1Zn0.1O10.7 were obtained after 4h sintering at 800 °C. Investigations were made about densification process and electrical conductivity related to the effect of addition of Zr0.88Y0.12O1.94.
