Mechanochemical synthesis of barium titanate

Thickness dependence on structural, dielectric and AC conduction studies of vacuum evaporated Sr doped BaTiO3 thin films

“…6 shows the XRD pattern of BST nanoparticles. From XRD measurement, the BST particle is exhibited to the tetragonal structure, because the peak splitting was found clearly in the (0 0 2) plane, which shows its high degree of tetragonality [15,16]. The average grain size (D) of the particle was calculated using scherrer's formula and it was found to be 66 nm.…”

High-temperature X-ray diffraction analysis and reactive sintering of BaTiO₃ piezoelectric ceramics

“…3)5) Various methods, such as solgel, 6) hydrothermal precipitation, 7) co-precipitation, 8) mechanochemical synthesis 9) and plasma spray coating, 10) have been investigated for the processing of BaTiO 3 powders and bulk ceramics. To utilize BaTiO 3 as a piezoelectric material, cation doping 11) and two-step sintering 12) are attractive techniques to improve the piezoelectric properties.…”

EFFECT OF MILLING TIME ON PHASE TRANSITION IN BaTi0.095W0.05O3 NANOCERAMICS SYNTHESIZED BY HIGH-ENERGY BALL MILLING

“…The properties of nanocrystalline materials are found superior those of polycrystalline coarse grained materials. Though literature survey shows that this novel technique has been used to synthesize several ferroelectric ceramics 15,16 , no reports were found on tungsten substitute barium titanate nanoceramics synthesized by mechanical activation method. This prompted the authors to synthesize the compound BaTi 0.95 W 0.05 O 3 by mechanical activation process and investigate their structural, dielectric, ferroelectric and piezoelectric properties.…”
