Cyclic Fatigue Mechanisms in New Lead-Free Piezoelectric Ceramics

Piezoceramics are an important component in many items in modern day Australian life. However, they present a growing environmental concern, particularly for disposal, because they contain lead oxide and must often be disposed of prematurely due to component failure. Furthermore, many key Australian industries manufacture and use piezoceramics in fields ranging from mineral exploration, to imaging to biomedical devices. This project will enable the development of lead-free alternatives to current materials and more reliable materials which will reduce the need for waste disposal.
