Sonochemical Synthesis and Characterization of Bismuth Aluminate Nanocrystals

Bismuth aluminate is a kind of antacid medicine which is used to treat peptic ulceration and nervous dyspepsia. In our experiment, a simple solution strategy via supersonic method for the synthesis of spherical bismuth aluminate nanoparticles at room temperature is presented. During the procedure, bismuth aluminate was directly precipitated from the solution in the ultrasonic syringe under strong alkaline condition and its chemical empirical formula was defined by inductively coupled plasma(ICP) analysis, element analyzer(EA) and analysis analysis. XRD, FTIR and TEM, have been employed to characterize the obtained nanocrystals. Preparative parameters, such as the pH value, drying temperature and the sonication time were optimized to obtain Bi2(Al2O4)3•10H2O nanomaterials with considerable yield, uniform shape and narrow size distributions.
