title: Syntheses of BaCO3 nanostructures by ultrasonic method.
abstract: BaCO3 nanostructures were synthesized by the reaction of Ba(CH3COO)2 and sodium hydroxide or tetramethylammonium hydroxide (TMAH) by a sonochemical method. Reaction conditions, such as the concentration of the Ba2+ ion, aging time and power of the ultrasonic device played important roles in the size, morphology and growth process of the final products. The BaCO3 nanostructures were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), and the Infrared spectroscopy (IR).
