Understanding nanostructure in lead-containing piezoceramics - the key to improved and environmentally-friendly materials

Lead-based piezoelectric ceramics are at present irreplaceable in many technological applications because of their exceptional properties. How these properties arise from the basic atomic-scale chemical interactions is a question of fundamental importance. We will use our world-leading X-ray and neutron diffuse scattering and computer-modelling methods to probe the local structure and dynamics of important piezoelectrics in a level of detail not previously achievable. This will provide information that has long been needed to make the crucial link between chemical make-up and physical properties. The understanding gained will allow better optimisation of existing materials and aid the search for more environmentally-friendly alternatives.
