abstract = {Several perovskite ceramics are known to have non-Arrhenius
type grain growth and to show grain growth transitions
instead. These growth transitions are coupled to bimodal
microstructures and seem to be caused by the existence,
coexistence and transition of two different grain boundary
types. This paper gives a review on the details of the grain
growth transitions in perovskite ceramics. A simple mean
field approach and standard grain growth experiments are
used for quantification. However, this approach is far too
simple to understand bimodal anisotropic grain growth
completely as apparent in perovskites. Important parameters
such as atomistic boundary structure, segregation effects,
wetting transitions, faceting, grain boundary stoichiometry,
space charge and interfacial drag effects are discussed with
respect to their impact on grain growth in perovskites. A
summary of open questions and future directions is given.},
