Abstract

Grain boundary structure was examined in 0.1 mol% TiO₂-excess BaTiO₃ by high-resolution electron microscopy (HRTEM) and electron energy loss spectroscopy (EELS). Their grain boundaries were mostly faceted with {210} type habit. The faceted boundaries were characterized to be associated with an extra Ti-O₂ bond with the rutile-like structure. The grain growth behavior in a small TiO₂-excess BaTiO₃ is discussed from the viewpoint of grain boundary structure.
