Influence of Pb(Al,Nb)O3 substitution on the structure and electrical properties in Pb(Zn,Nb)O3-Pb(Zr,Ti)O3 solid solutions

In this work, the solid solutions of 0.8Pb(Zr0.52Ti0.48)O3−(0.2−x)Pb(Zn1/3Nb2/3)O3−xPb(Al1/2Nb1/2)O3 (PZT-PZN-xPAN) were designed and fabricated via the traditional solid state reaction method. The dielectric, ferroelectric, piezoelectric properties of PZT-PZN-xPAN solid solutions were investigated in detail. The optimum electric properties of Pm = 46.3 μC/cm2, Pr = 42 μC/cm2, Pr/Pm = 90.5%, Stotal = 0.48%, d33 = 410 pC/N, and Tc = 283 °C were achieved in PZT-PZN-xPAN ceramics with x = 0.02. A large strain response of ∼0.24% with normalized strain Smax/Emax as high as 767 pm/V was obtained for the PZT-PZN-0.1PAN under a low electric field of ∼3 kV/mm at room-temperature.
