Calcia stabilized zirconia ceramics was manufactured from freeze-dried nanopowder by annealing of compacted samples at 1823K for 3 hours. Structure and composition of samples were investigated by SEM, EDX, and XRD analysis. Electrical properties of ceramics were investigated via impedance spectroscopy technique in the range 556-1033K. It was shown that the conductivity of xCaO-(100-x)ZrO2 (x=9 and 12 mol.%) ceramics is ∼10-2 S/cm at 1000K. Temperature dependencies of grain and grain boundary conductivity were obtained for all ceramic compositions. The values of activation energies of conductivity and blocking coefficients showed that grain boundaries in ceramics are thin and discontinuous. The mechanism of conductivity in CaO-ZrO2 system was suggested.",

Temperature dependencies of grain and grain boundary conductivity were obtained for all ceramic compositions. The values of activation energies of conductivity and blocking coefficients showed that grain boundaries in ceramics are thin and discontinuous. The mechanism of conductivity in CaO-ZrO2 system was suggested.
