Atmosphere- and Voltage-Dependent Electronic Conductivity of Oxide-Ion-Conducting Zr1-xYxO2-x/2 Ceramics
Jovaní, Marc; Beltrán Mir, Héctor; Cordoncillo, Eloisa; West, Anthony R. ACS (2017-05)Cubic, fluorite-structured solid solutions Zr1-xYxO2-x/2 (YSZ; x = 0.4-0.7) were prepared by sol-gel synthesis. Impedance measurements on pellets of 85% approximate density sintered at 1300 °C for 24 h showed strong evidence ... -
Environmental-friendly red-orange ceramic pigment based on Pr and Fe co-doped Y2Zr2O7
Jovaní, Marc; Fortuño-Morte, Maria; Beltrán Mir, Héctor; Cordoncillo, Eloisa Elsevier (2017-12)A new environmental-friendly red-orange ceramic pigment based on the general formula Y2-xPrxZr2-yFeyO7-δ was prepared by polymeric sol-gel method at 1400 °C. The solid solution range with defect fluorite structure ... -
Field-induced p-n transition in yttria-stabilized zirconia
Jovaní, Marc; Beltrán Mir, Héctor; Cordoncillo, Eloisa; West, Anthony R. Nature (2019)Oxide ion conducting yttria-stabilised zirconia ceramics show the onset of electronic conduction under a small bias voltage. Compositions with a high yttria content undergo a transition from p-type to n-type behavior at ... -
New red-shade environmental-friendly multifunctional pigment based on Tb and Fe doped Y2Zr2O7 for ceramic applications and cool roof coatings
Jovaní, Marc; Sanz, Ana; Beltrán Mir, Héctor; Cordoncillo, Eloisa Elsevier (2016)A new red-shade environmental friendly ceramic pigment with the general formula Y2−xTbxZr2−yFeyO7−δ [x = 0, 0.25 and y = 0.15, 0.25, 0.35] was prepared by a polymeric sol-gel process and after calcination at 1300 °C for ...
