Durá, O. J. ; López de la Torre, M. A. ; Vázquez, L. ; Chaboy, J. ; Boada, R. ; Rivera Calzada, Alberto Carlos ; Santamaría Sánchez-Barriga, Jacobo ; León Yebra, Carlos | American Physical Society | 2010-05-01We report on the effect of grain size on the ionic conductivity of yttria-stabilized zirconia samples synthesized by ball milling. Complex impedance measurements, as a function of temperature and frequency are performed on 10 mol % yttria-stabil[...]texto impreso
Durá, O. J. ; Boada, R. ; Rivera Calzada, Alberto Carlos ; León Yebra, Carlos ; Bauer, E. ; López de la Torre, M. A. ; Chaboy, J. | American Physical Society | 2011-11-24This work reports on the effect of grain size on the electrical, thermal, and structural properties of CuAlO_(2) samples obtained by solid-state reaction combined with ball milling. Electrical characterization made in microcrystalline and nanocr[...]texto impreso
Durá, O. J. ; Boada, R. ; López de la Torre, M.A. ; Aquilanti, G. ; Rivera Calzada, Alberto Carlos ; León Yebra, Carlos ; Chaboy, J. | American Physical Society | 2013The local order around Zr and Y atoms of nanocrystalline yttria-stabilized zirconia (YSZ) powders with different grain sizes has been investigated by x-ray absorption spectroscopies. The samples were prepared by means of mechanical alloying with[...]
