abstract |
In the past ten years a series of developments in the field of materials with dominant oxygen ion conduction introduced a variety of new systems. The most relevant aspect is a shift from ionic transport mechanisms based on the motion of oxygen vacancies, to mechanisms based on mobile oxygen interstitials. In parallel, structures identified with dominant oxygen ion conduction moved from the relatively simple fluorite related ones to more complex materials, namely with the apatite-type and related structures, including coexistence of ionic and covalent bonding. This shift is understood as a major development, opening a wide range of alternative solutions for further exploitation. |
