Spatially Varying Properties of Highly Resistive Grain Boundaries

1 Spatially Varying Properties of Highly Resistive Grain Boundaries 

Serious problems with respect to a quantitative analysis can occur if the assumption of identical grain boundaries is violated. In sintering processes, inhomogeneities are the rule rather than the exception and grain boundary cores in one and the same polycrystal can easily differ in terms of structure and chemistry [109, 120, 242-246], Hence, core as well as space charge conductivities might also vary from boundary to
