Dielectric and ferroelectric properties of fine grains Pb(In1/2Nb1/2)O3-PbTiO3 ceramics
چکیده انگلیسی
The dielectric and ferroelectric properties of (1 − x)Pb(In1/2Nb1/2)O3-xPbTiO3 (when x = 0.1, 0.2, 0.3, 0.4, and 0.5) ceramics prepared by an oxide-mixing method via a vibro-milling technique were investigated. Fine grains ceramics were achieved with average grain size of 1-2 μm, indicating advantage of the vibro-milling technique used. While PIN ceramic exhibited relaxor behavior, the dielectric properties of PIN-PT ceramics showed a mixed relaxor and normal ferroelectric behavior, with more normal ferroelectric behavior observed with increasing PT content. In addition, the ferroelectric properties of the ceramics in PIN-PT system changed from the relaxor ferroelectric behavior in PIN ceramic to the normal ferroelectric behavior in PIN-PT ceramics. These results clearly show the significance of the added PT in reducing the relaxor ferroelectric behavior in PIN ceramic. Finally, the existence of the MPB composition between x = 0.3 and 0.4 has been confirmed from the XRD analysis, and dielectric and ferroelectric properties measurements.
