“…Adam et al [11] proposed the use of a solvothermal method instead of the hydrothermal one for the preparation of smaller and defect-less BT nanoparticles, in which aqueous solution are replaced with organic solvents. Similar studies were conducted by Kwon et al [12], Habib et al [13].…”

In order to synthesize of high-dispersion and tetragonal BaTiO 3 (BT) nanoparticle, a hydrothermal method is used in a mixture of chloride metal sources and KOH with polyvinylpyrrolidone (PVP). The properties of BT-PVPs prepared by different reaction temperature and time are investigated via XRD, FE-SEM, DLS, FT-IR, and TEM to clarify the changes of the crystal phase, dispersion, and particle structure. The reaction is finished at 230 • C for 24 h and the critical reaction condition for that the crystal phase of the obtained BT particle changed from the cubic to the tetragonal is found to be 190 • C fixed in reaction time 24 h, and 9 h. During reaction the PVP on the BT surface decomposed to different form, and the PVP plays the role of dispersant in aqueous solution. By the hydrothermal condition of 230 • C for 24 h almost monodisperse BT-PVP with sizes of 83 nm and tetragonality (c/a) of 1.0062 were synthesized. The structure of nanoparticle, core (BT)-shell (PVP) was investigated by FT-IR and direct observed by TEM and the mechanism of particle growth and dispersion was discussed.

“…The solvothermal systems with alcohol or alcohol/water solvents were studied for the preparation of superfine or tetragonal BaTiO 3 powders. The authors mainly agreed about the decrease in the BaTiO 3 particle size with the increase in alcohol content, whereas their observations regarding tetragonality were often contradictory . In an earlier study, Chen and Jiao reported that alcohols (ethanol, methanol, and n‐propanol) had a detrimental effect on the tetragonal phase formation .…”

The Morphology Control of BaTiO₃ Particles Synthesized in Water and a Water/Ethanol Solvent

The experimental conditions for the growth of shape-controlled BaTiO 3 particles in NaOH and Ba(NO 3 ) 2 aqueous and water/ ethanol solutions using various TiO 2 -containing precursors were studied at 80°C-100°C. The different chemistries and physical characteristics of the precursors resulted in different BaTiO 3 formation rates and morphologies . Nanocrystalline anatase led to irregularly shaped BaTiO 3 particles, whereas star-like, single-crystalline BaTiO 3 particles grew from aerogel TiO 2 and sodium titanate (NT) belts in alkaline aqueous solutions. With the addition of ethanol, the star-like BaTiO 3 particles changed to square-like, the size of which decreased with an increase in the ethanol content. The electron microscopy observations supported a dissolution-precipitation mechanism as the primary reaction mechanism for the formation of BaTiO 3 nanocrystals, which further aggregated into single-crystalline star-or square-like particles by oriented attachment. The modification in the water solution with ethanol is believed to influence both the nucleation and aggregation process and consequently influence the particle shape and size.M.

“…The dielectric properties of BaTiO 3 are controlled by purity and microstructure, which are dependent on the methods of preparation [3][4][5]. Controlling the phase, composition homogeneity, particle size and monodispersity are other concerns in developing techniques for synthesizing barium titanate [6].…”

In this study, we present the results of the manufacturing of BaTiO 3 powder, which is meant for use in stackeddisk multilayer actuator production. The solid-state technique was used for powder preparation. The properties of barium titanate material, at each stage of its fabrication (powder, granulate, sintered material), influencing on its application for the stacked-disk multilayer actuator were determined. Particularly, the four parameters of BaTiO 3 sinter affecting on the usability properties of actuators, not found before in the literature, were estimated. Parameters characterizing the extent of material sintering, SEM microstructures and electric properties of the fabricated pellets are presented and discussed. The dilatometric curve was executed using the high temperature dilatometer to determine at which temperature barium titanate pellets and beams should be sintered to receive full dense sinters. Parameters characterizing the extent of material sintering: the apparent density, the apparent porosity and the water absorbability were estimated. Finally, the problem of metal layer deposition on barium titanate ceramics during actuator fabrication is considered.
