Lead-Free Ceramic Materials for Pulsed Power Applications (Ref: FP-FI-2026R)
About the Project
This interdisciplinary PhD project will develop lead-free ferroelectric ceramics for compact, explosively driven pulsed power systems. The research addresses the critical challenge of replacing high-performance but environmentally problematic lead-based ceramics with sustainable alternatives capable of reliable operation under extreme dynamic conditions.
Explosively driven pulsed power systems convert mechanical shock energy into high-power electrical pulses, enabling lightweight, compact, and ultra-fast power sources for advanced electromagnetic and directed energy applications. These systems rely on ferroelectric ceramics that store and rapidly release electrical energy when subjected to shock-induced depolarisation.
Lead-based materials, such as lead zirconate titanate (PZT), have long set the benchmark for electromechanical performance. However, environmental, and regulatory pressures have created an urgent need for high-performance lead-free alternatives. Recent advances suggest some emerging lead-free ferroelectric compositions can match or surpass lead-based performance, offering improvements in both sustainability and capability.
The project will begin with a literature review to identify promising lead-free ferroelectric systems. Selected compositions will be synthesised using advanced ceramic processing, including solid-state reaction and field-assisted sintering, to achieve high density and controlled microstructure. Materials will then be poled under high voltage and elevated temperature before structural, dielectric, and ferroelectric characterisation.
The most promising materials will undergo controlled shock-loading experiments in specialised pulsed power facilities to evaluate depolarisation behaviour, energy extraction efficiency, and durability under realistic dynamic conditions. The successful applicant will collaborate with the Plasma and Pulsed Power Group and the Advanced Ceramics Research Group, both internationally recognised for expertise in explosively driven pulsed power, functional ceramics, and advanced processing.
