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.
