Abstract:
Lead zirconate titanate [Pb(ZrxTi1−x)O3 (PZT)] powders and ferroelectric thin films with a composition near the morphotropic phase boundary [Pb(Zr0.52Ti0.48)O3] were prepared by a modified sol-gel process using zirconium oxynitrate-2-hydrate as the zirconium source and ethylene glycol as solvent. The precursor solution was prepared from lead acetate-3-hydrate, tetrabutyl titanate, and zirconium oxynitrate-2-hydrate. Perovskite PZT powders were obtained after sintering at 450 °C for 2 h. Films rapid-thermally annealed at 650 °C for 1 min formed well-crystallized perovskite.Microstructures of th

Abstract:
Perovskite type oxyhydrides, of the form ATiO3-xHx (A = Ba, Sr, and Ca, and x < 0.6) are a novel class of mixed-anion materials displaying high hydride-ion conductivity. The high hydride-ion conductivity may be exploited for applications such as in energy storage and conversion devices, and in catalyst technologies for hydrogenation reactions, bu the conductivity mechanism is not fully understood. Here, in a quasielastic neutron scattering study of the oxyhydride of barium titanate, with different levels of anion vacancies, we show that the rate of hydride-ion diffusion increases with an in
