Abstract

Representative samples of piezoceramic materials have been examined in the Scanning Electron Microscope. The microstructures have been compared and contrasted in terms of porosity, grain sizes and grain size distributions, homogeneity and pore size. Samples with typically hard and soft piezoelectric responses, manufactured by conventional powder processing and atmospheric sintering have been analysed and compared to a soft piezoceramic that has been hot pressed. Generally, all the samples showed some porosity, were homogeneous in phase identity, and were readily etched to delineate the grain boundaries.
