Abstract
Ceramic specimens of BaO . Pr2O3. 4TiO(2) (Ba4.5Pr9Ti18O54) were prepared b y the mixed oxide-route. The single phase products were examined by High Re solution Transmission Electron Microscopy (HRTEM). Orthorhombic symmetry, w ith cell parameters a similar to 22.2 Angstrom, b similar to 12.2 Angstrom and c similar to7.6 Angstrom, was confirmed. On the basis of space group pn am (No. 62) and the crystal structural data of Rawn et al., good agreement was obtained between the experimental HRTEM images and images simulated by the multislice method.
