Hydrothermal Synthesis and Dielectric Properties of Tetragonal BaTiO3

The effect of processing conditions on the morphology, thermomechanical, dielectric, and piezoelectric properties of P(VDF-TrFE)/BaTiO3 composites

“…2) showed for both powders a peak at 129°C upon heating (inset in the figure) and a peak at 120°C upon cooling, that can be attributed to the transition from the tetragonal piezoelectric phase to the cubic paraelectric phase and vice versa (Curie temperature, T c ) of BaTiO 3 . The DH of the transition was greater for BT-2 (DH = 0.4 J/g) than for BT-1 (DH = 0.2 J/g), indicating higher amount of tetragonal phase in the BT-2 powder [48,49].…”

Low-temperature Synthesis of Highly Crystalline BaxSr1-xTiO3Nanoparticles in Aqueous Medium

“…These precursors are water-soluble and are expected to form metal cation in water, as shown in equation (4) ) to form the polymeric inorganic chain structure, because of the high nucleophilicity of the TiO -anionic species, as described in equation (5). Then the inorganic polymerization reactions proceed continuously to form sufficiently large particles with desired compositions and sizes.…”

“…It is well-known that these properties critically depend on their chemical compositions and structural characteristics. [3][4][5][6][7][8][9] That is, the electrical and electronic properties of BaTiO 3 , SrTiO 3 and Ba x Sr 1-x TiO 3 (BST) can be modified according to the Ba content in the solid solution, crystallinity, particle size and shape, and others. For instance, their ferroelectric Curie temperatures can be tuned by changing the strontium to barium ratio in BaxSr1-xTiO3.…”

Lead Titanate-Based Nanocomposite: Fabrication, Characterization and Application and Energy Conversion Evaluation

“…The key factors in this method are the vapor pressure and solubility of the chemical salts in water [LENCKA 1995]. In contrast to the conventional hydrothermal method which requires a long time typically several days and high electric power (over thousand watts) [DUTTA 1994], microwave-assisted heating is a greener approach to synthesize materials within a shorter time typically several minutes to some few hours less than the duration of the conventional method and with lower energy consumption (hundreds of watts). The desired PZT product can be synthesized using Pb(NO 3 ) 2 , ZrOCl 2 .8H 2 O, TiO 2 , KOH .…”
