Реферат: eng: Studies of mechanochemical powders and sintered ceramics in scandia stabilized zirconia system have been carried out by means of XRD technique, Raman spectroscopy and SIMS. Nanostructured single phase ceramics of Zr0.88Sc0.1Ce0.01Y0.01O1.955 composition with the room-temperature rhombohedral structure caused by ordering of oxygen vacancies possesses excellent mechanical strength and unusual conductivity properties with Eb ∼ Egb. Decreased level of conductivity at T ∼ 1000 K was explained by incomplete stabilization of cubic phase and admixtures of silica and alumina present in starting ZrO2 reagent of technical grade. © 2009.
