Hydrothermal synthesis of perovskite bismuth ferrite crystallites

Effects of Mn Doping on Structural and Magnetic Properties of Multiferroic BiFeO3Nanograins Made by Sol-gel Method

“…3 shows the magnetization curve of the BiFeO 3 and BiFe 0.8 Mn 0.2 O 3 nanograins measured at 300 K with an applied field of 10 KOe. A typical magnetic hysteresis loop was observed, indicating that the BiFeO 3 nanograins show a weak ferromagnetic order at room temperature, which is quite different from the linear M-H relationship observed in the bulk BiFeO 3 [17,18]. The similar ferromagnetic phenomenon was also observed in BiFeO 3 films [19], nanotubes [17] and nanocrystallites [20].…”

Hydrothermal Synthesis of BiFeO₃ Fine Particles

“…Figure 1 shows X-ray powder diffraction patterns of the products at 180 ºC. The X-ray powder pattern of the product under the condition of K/Bi = 5 and 180 ºC was very similar to that of the product prepared by hydrothermal reaction of NaBiO 3 8) . This difference may come from the reaction duration; our hydrothermal reactions were carried out for long time (48h.)…”

“…BFO perovskite could only stabilize within a narrow ranged temperature. Hydrothermal reaction and sol-gel method are useful to obtain a pure powder sample with uniform particle size [8][9][10][11][12] . So far there have been many papers for hydrothermal synthesis of BFO.…”

Fabrication of BaTiO₃/BiFeO₃ Nano-complex Ceramics by Hydrothermal Method

“…We prepared BF particles by the hydrothermal method [11][12][13]. The BF particles and titanium oxide nano-particles (TiO 2 , rutile-type structure, particle size of approximately 7 nm, Ishihara Sangyo Kaisya, Ltd.) were mixed with an organic binder, poly(vinyl butyral) (2 wt%), and ethanol, and TiO 2 /BF molar ratios were adjusted to 0.25, 0.50, 0.75, and 1.00.…”
