Abstract:

Explosive pulsed powers (EPP) based on the shock-compression-induced depolarization effect of ferroelectric or piezoelectric ceramics are found important applications in the area of high pulsed power supplies. A particular lead titanate-lead zircaonate (PZT) solid solution with a Zr : Ti ratio of 95 : 5, denoted by PZT95/5, was identified as a promising material for this application. Recently, porous PZT95/5 ferroelectric ceramics are attracting more attention due to their enhanced performance under shock compression. In this article, progress of porous PZT95/5 ferroelectric ceramics in the past decades were reviewed. The dependence of porous microstructures, such as porosity, pore size and morphorlogy, pore distribution on the property were emphasized. Porous PZT95/5 ferroelectric ceramics with specific porous microstructure was found exhibiting superior performance under shock wave compression. Theoretical and experimental results found the mesoscopic mechanism for porous PZT95/5 ferroelectric ceramics to exhibit excellent shock damage resistance. In the final section, new ferroelectric candidates, such as BNT-based ferroelectric ceramics and PIN-PMN single crystal, for EPP application were also reviewed and prospective research work in the future is proposed.
