Phase structures of two ceramics of compositions BaNd/sub 2/Ti/sub 5/O/sub 14/ and Ba/sub 3.75/Nd/sub 9.5/Ti/sub 18/O/sub 54/, both of which had earlier been reported to be single-phase materials, were investigated using electron microscopy and an electron probe microanalyzer. It was observed that the amount of secondary phases was much lower in ceramics prepared with the latter composition and that the composition of the matrix phase of both samples was near 4BaO . 5Nd/sub 2/O/sub 3/ . 18TiO/sub 2/.
