Structural transformation in antiferroelectric PbZrO3-relaxor ferroelectric Pb(Ni1∕3Nb2∕3)O3 solid solution system

Abstract

The solid solution between the antiferroelectric (AFE) PbZrO3 (PZ) and the relaxor ferroelectric (FE) Pb(Ni1∕3Nb2∕3)O3 (PNN) was synthesized by the columbite precursor method. The crystal structure, phase transformations, and dielectric and thermal properties of (1−x)PZ-xPNN where x=0.00–0.30 were investigated. With these data, the FE phase diagram between PZ and PNN has been established. The crystal structure data obtained from X-ray diffraction indicate that the solid solution PZ-PNN, where x=0.00–0.30, successively transforms from orthorhombic to rhombohedral symmetry with an increase in the PNN concentration. The AFE phase→FE phase transition occurs in compositions of 0.00⩽x⩽0.08. The AFE→FE phase transition shifts to lower temperatures with higher compositions of x. The FE phase temperature range width increases with increased PNN. Apparently the replacement of the Zr4+ ion by Ni2+∕Nb5+ ions decreases the driving force for an antiparallel shift of Pb2+ ions because they interrupt the translational symmetry and facilitates the appearance of a rhombohedral FE phase when the amount of PNN is higher than 8mol%.

Phase transitional behavior and dielectric properties of lead free (1−x)(K0.5Na0.5)NbO3−xBi(Zn0.5Ti0.5)O3 ceramics

“…Choi et al [22] reported that in the Bi(Ni 1/2 Ti 1/2 )O 3 -PbTiO 3 (BNiT-PT), the tricritical point in the solid solution also corresponded closely to t ∼ 1.0. Similar phenomena have been observed in the Bi(Mg 3/4 W 1/4 )O 3 -PbTiO 3 (BMW-PT) system by Stringer et al [23] and our previous work on PbZrO 3 related materials [24,25].…”

Effect of BiAlO3 modification on the stability of antiferroelectric phase in PbZrO3 ceramics prepared by conventional solid state reaction

“…[8,10] or (Pb,Ba)ZrO 3 [5,7]. Nevertheless, at high temperature, the dielectric data revealed an enhanced dielectric loss with increasing BAO concentration.…”

“…The FE intermediate phase can be induced by adding Ba 2+ , Sr 2+ , and La 3+ at the Pb 2+ -site [2,[4][5][6][7]. Moreover, our recent research found that the FE intermediate phase also can be induced by adding, for example, hybrid-doped Ni 2+ /Nb 5+ , Zn 2+ /Nb 5+ , Co 2+ /Nb 5+ and Mg 2+ /W 6+ at the Zr 4+ -site [8][9][10][11][12][13][14]. BiMO 3 ; M = Fe 3+ , Mn 3+ and Nd 3+ has received a lot of attention recently as a multiferroic, and investigation of the solid solutions, BiMO 3 -PbTiO 3, has shown that they improve ferroelectric properties of PbTiO 3 , reduce the amount of lead, and find new morphotropic phase boundary piezoelectrics [15][16][17][18].…”

The phase evolution with temperature in 0.94PbZrO3–0.06Pb(Mg1/2W1/2)O3 antiferroelectric ceramic

“…Recently, our research work reported that the intermediate phase can also be introduced by partial replacement of Zr 4+ ions with complex B-site ions such as Ni 2+ /Nb 5+ [23,24], Zn 2+ /Nb 5+ [25], or Co 2+ /Nb 5+ [26]. Furthermore, our previous study found that by adding minor amounts (2-10 mol%) of antiferroelectric Pb(Mg 1/2 W 1/2 )O 3 (PMW) into antiferroelectric PZ, the temperature range expanded to an intermediate phase, which was characterized by evident frequency dispersion in dielectric permittivity [27].…”
