      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.},
