Hydrothermal Synthesis of Sodium and Potassium Bismuth Titanates
Chemistry of Materials, 2000A thermodynamic model of electrolyte solutions has been used as a tool for equilibrium calculations in the Na−Bi−Ti−H2O and K−Bi−Ti−H2O systems. To perform the calculations, unknown standard-state properties for Na0.5Bi0.5TiO3 (NBT), K0.5Bi0.5TiO3 (KBT) and other solid compounds that exist in these systems were established.

Sodium-bismuth titanate based lead-free ferroelectric materials
Journal of the European Ceramic Society, 2004Abstract In search of lead-free ferroelectric ceramics with improved properties, an investigation was carried out on barium and strontium-modified Na0.5Bi0.5TiO3 (NBT) ceramics. Many compositions among the Ba and Sr-modified ceramic materials exhibit diffuse phase transition and are characterised by a strong temperature and frequency dispersion of ...

Electromechanical Characterization of Lanthanum Doped Sodium Bismuth Titanate Ceramics
Ferroelectrics, 2005The effect of lanthanum doping is studied on electromechanical properties of lanthanum doped sodium bismuth titanate. The ferroelectric system under investigation is Na1/2 (La x Bi 1−x )1/2 TiO3 ceramics, with x = 0, 0.1, 0.15 and 0.2. Dielectric and impedance studies have been carried out in the temperature region ranging from room temperature to 550 ...

Characteristics of yttrium substituted sodium bismuth titanate thin films
Materials Letters, 2010Abstract Sodium bismuth titanate (NBT) thin films substituted with yttrium for Na site were prepared by a modified sol–gel processing and their dielectric properties were investigated. The stability of perovskite structure was highly affected by the amount of Y substitution and the annealing temperatures. Y substituted NBT thin films post-annealed at
