Resource type: Image
Description: The image shows a single representative grain within the polycrystalline ceramic. The core region shows ferroelectric domains from the pure, tetragonal BaTiO3 centre. The shell region contains Nb and Bi dopant which make it cubic, paraelectric and also stacking faults associated with their presence. The heterogeneous nature of the microstructure confers the temperature stability on the ceramic.
