Solid electrolytes with oxygen ion conduction
Solid State Ionics, 1984Abstract Oxygen ion conductors constitute an important class of solid electrolytes and have been extensively studied from scientific and technological standpoint. Most of the oxygen ion conductors (eg. those based on ZrO2, ThO2, CeO2 and Bi2O3) have a perfect or distorted fluorite type structure.

Microstructural aspects of oxygen ion conduction in solids
Solid State Ionics, 2000The microstructure of solid electrolyte ceramics plays a key role in defining the level of ionic conduction of the material. The polycrystalline nature and the metastable state of most practically useful materials require that the conducting ion must negotiate a series of interfacial features during the conducting process.

Oxygen-ion conductivity and catalysis
Solid State Ionics, 2000Abstract Oxygen-ion conducting solid electrolyte electrochemical cells were prepared with both Fe 2 O 3 –Sb 2 O 4 and Pt working electrodes. The working electrode served as both catalyst, for a heterogeneous catalytic reaction taking place in the electrode compartment, and electrode.

Ionic conductivity of oxygen ions in YBa2Cu3O7−x
Solid State Ionics, 1989Abstract The ionic conductivity of oxygen ions in YBa 2 Cu 3 O 7 −x has been measured at constant partial pressure of oxygen as a function of temperature between 300 and 500°C. A four-probe dc technique was applied with four oxygen-ion conducting electrodes.

Oxygen ion conduction in ?-Bi2O3 doped with Sb2O3
Journal of Materials Science, 1986Electrical conduction in bccγ-Bi2O3 doped with Sb2O3 was investigated by measuring electrical conductivity, as a function of temperature and oxygen partial pressure\(P_{{\text{0}}_2 } \), and ionic transference number. Theγ-Bi2O3 doped with 1 to 3 mol% Sb2O3 was stable up to 550° C and showed an oxygen ionic conduction in the\(P_{{\text{0}}_2 ...

Oxygen ion conduction and structural disorder in conductive oxides
Journal of Physics and Chemistry of Solids, 1994Abstract Defect-free crystals do not conduct ions. Increasing disorder initially translates into enhanced atomic transport. Heavily defective crystals, however, often exhibit successively lower levels of atomic diffusivity as the defect level is increased.

Synthesis, Densification, and Conductivity Characteristics of BICUVOX Oxygen‐Ion‐Conducting Ceramics
Journal of the American Ceramic Society, 1997Copper‐substituted bismuth vanadate (Bi 2 V 0.9 Cu 0.1 O 5.35 ), known as BICUVOX, possesses high oxygen ion conductivities at low temperatures.

Electrical Conduction by Oxygen Ions in Cerium Oxide
The Journal of Chemical Physics, 1966Oxygen gas was observed by means of a mass spectrometer to be evolved from calcium-doped ceramic cerium oxide when direct current was passed through it at 450°C. The applied voltage necessary to cause the electrolysis was about 100 V across a sample 4 mm long containing 0.86 at. % calcium.

Protonic and oxygen-ion conduction in SrZrO3-based materials
Journal of Materials Science, 1995Strontium zirconate-based materials have been studied as potential high-temperature protonic conductors. Yttrium for zirconium substitution, and lanthanum for strontium substitution were selected to demonstrate that changes in composition can be used as a tool to design the properties. At temperatures below about 900 ° C, both yttrium-doped and undoped
