Abstract
When processing ceramics, some crystallites develop to enormous sizes compared to the majority of other grains. This effect, known as anisotropic grain growth, is the main source of inhomogeniety in polycrystalline materials and markedly influences physical properties of the product. Based on our observations in several oxide ceramic systems we propose, that both, generic nature and growth of such grains are ruled by chemically driven formation of faulted structure within. Local structure and chemistry of these faults are always common to that of the host crystal and to an existent equilibrium thermodynamic phase.
