BaTiO3 nanocrystals: Hydrothermal synthesis and structural characterization

Facile synthesis of SrTiO3 hollow microspheres built as assembly of nanocubes and their associated photocatalytic activity

“…4. It is known that in the perovskite structure, the {1 0 0} planes own the lowest surface energy, and in turn have the lowest planar growth rate [28]. Thus, the equilibrium shape is cubic, as observed in other perovskites [29].…”

Hydrothermal technology for nanotechnology

“…The change in experimental temperature and experimental duration also changes the size and shape of the particles. The average particle size varies from 30 AE 5 to 80 AE 10 nm obtained in a temperature range 180e 240 C in about 3 h. Zhu et al have synthesized BaTiO 3 nanocrystals under hydrothermal conditions [159]. Barium titanate nanocrystals were synthesized using titanium hydroxide and barium hydroxide as starting materials.…”

Synthesis of Nano‐sized BaTiO3 Powders by the Rotary‐Hydrothermal Process

“…Recently, wet chemical processes such as the sol-gel method, [5][6][7] homogeneous precipitation (the oxalic acid method), 8 and the hydrothermal method [9][10][11][12][13] have been developed to improve the homogeneity and purity of BaTiO 3 powders. Because products prepared by solution-based processes such as the sol-gel method and homogeneous precipitation either are amorphous or represent precursor compounds, a heattreatment step at temperatures above 923 K is required in order to remove unreacted organics and form a pure crystalline phase.…”
