The reaction sequence in the BaTiO3-Nb2Os-Bi203 system leading to the core-shell microstructure that causes the temperature-stable dielectric response has been examined using X-ray diffraction. The starting oxides react to form bismuth oxide layer Aurivillius phases at low temperatures which, inturn
