Hydrothermal Synthesis of Nano-Structured Barium Titanate from Metatitanic Acid
Nano-structured Barium Titanate (BaTiO3) was prepared by a hydrothermal method with the reaction between metatitanic acid and an alkaline solution of Ba(OH)2•8H2O. The morphology of as-obtained powders of BaTiO3 was determined by Scanning Electron Microscope, which revealed that well-dispersed nanoparticles were successfully synthesized. The phase composition was analyzed by X-ray diffraction, which shows that cubic phase of Barium Titanate was prepared. The optimal reaction conditions were discussed in detail.
