Abstract: The behaviour of lattice parameter of ZrO2 + 12 mole % Y2O3 as a function of cobaltic oxide addition (0.1-0.5 mass To Co2O3) allows to assume the formation of two types of solid solutions, substitutional and interstitial and their mutual coexistence at w > 0.3 mass % Co2O3 The crystallographic ordering of oxygen sublattice according to this structural model results in the maximum of electrical conductivity observed at ≈ 0.1 mass % Co2O3 and the corresponding changes in the Raman spectra and in the shape of infrared modes.
