Cyclic Fatigue Mechanisms in New Lead-Free Piezoelectric Ceramics

压电陶瓷是现代澳大利亚生活中许多项目的重要组成部分。然而，它们提出了越来越多的环境问题，特别是对于处置，因为它们含有氧化铅，并且由于组件故障而必须经常过早地处置。此外，澳大利亚的许多关键行业制造和使用压电陶瓷，从矿产勘探到成像到生物医学设备。该项目将开发无铅替代品，以取代目前的材料和更可靠的材料，从而减少废物处理的需要。

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.
