摘要：

Solid solutions of (1-x)PbZrO3-xBa(Mg1/3Nb2/3)O-3 (PZ-xBMN, x = 0.02, 0.03, 0.04, and 0.05) were prepared, and their microstructures, electrical properties, and phase transition behaviors under hydrostatic pressure were investigated. It was found that the incorporation of BMN into PZ can provide improved ferroelectric properties, leading to the formation of antiferroelectric/ferroelectric phase boundaries in PZ-xBMN ceramics when the value of x is between 0.02 and 0.03. It was also demonstrated that the ferroelectric phases exhibit excellent temperature stability in the remanent polarization. Importantly, complete depolarization was observed in the PZ-xBMN solid solution due to the hydrostatic pressure-induced ferroelectric-antiferroelectric phase transition. The resultant properties and phase transition behaviors of PZ-xBMN ceramics under pressure will benefit their application in pulsed power supplies.
