Oxide structures contain two or more sublattices in a prototypical array that defines the ideal dielectric, magnetic, and electronic structure. The requirements of symmetry and charge neutrality require that the creation of a defect, a change on one ionic or structural sublattice, be reflected in a balancing change on one or more of the other ionic or structural sublattices or through the creation of a charged electronic defect. Owing to the requirement of continuous charge balance and conservation of lattice symmetry and continuity, reaction and corrosive interaction is relatively slow in close-packed ionic lattices and relies on the preexistence of defects to progress.
