An analyze of the transport processes in oxides, under a constant or variable (cooling) temperature gradient, has been performed in order to show the conditions leading to surface morphological instabilities and segregations. Because the properties of ceramics are often influenced by the presence of dopants or imputities and by their microstructure, these effects can severely alter the properties of materials and can be an important cause of ageing of ceramics when they are used at high temperature.<
