Abstract
Grain boundary structure was examined with HRTEM and EELS for BaTiO3 doped with a small amount of cations with a special interest in chemical bonding state. It was found that the grain boundary structure was sensitive to a small excess of Ti-site dopant. The grain boundaries arc facetted with {210} habits and an ordered structure is formed. HRETM and EELS examination combined with molecular orbital calculation clearly revealed that TiO6 octahedral linkage changes from corner-sharing in the grain interior to edge-sharing at the grain boundary.
