This paper uses the complementary techniques of high resolution Z-contrast imaging and PEELS (parallel detection electron energy loss spectroscopy) to investigate the atomic structure and chemistry of a 25 degree symmetric tilt boundary in a bicrystal of the electroceramic SrTiO{sub 3}. The gain boundary is composed of two different boundary structural units which occur in about equal numbers: one which contains Ti-O columns and the other without.
