Synthesis of slightly 〈1 1 1〉-oriented 0.65Pb(Mg1/3Nb2/3)O3–0.35PbTiO3 ceramic prepared from fine powders

Slightly 〈1 1 1〉-oriented 0.65Pb(Mg1/3Nb2/3)O3–0.35PbTiO3 ceramic was prepared using fine powders obtained by means of an alternative and promising chemical oxide precursor method. High quality samples with improved structural, microstructural, dielectric and ferroelectric properties were obtained. The dielectric constant value (ɛ ∼ 2577) measured at 1 kHz is compared to unpoled 〈1 1 2〉 grain-oriented ceramics while the remanent polarization (Pr ∼ 19.1 μC cm−2) is compared with random grain-oriented ceramics. These results point out the viability to produce ferroelectric PMN-PT ceramics of very good quality using powder precursors prepared from this chemical method.
