MUCCILLO, E. N. S.. Oxygen-ion conductors: a brief review. Cerâmica [online]. 2008, vol.54, n.330, pp.129-144. ISSN 1678-4553. http://dx.doi.org/10.1590/S0366-69132008000200002.
The main characteristics related to transport properties of oxygen ion conductors are described in detail. The materials focused are those based on zirconia and ceria solid solutions, compounds with pyrochlore and perovskite-type structures, and the most recently reported ionic conductors based on apatite structure and those derived from La2Mo2O9 composition. Particular emphasis will be paid on recent results. The main purpose of this review is to summarize the most relevant aspects related to transport properties, allowing for a critical analysis of the potential of application of these ceramic solid electrolytes.
