Preparation of Aluminum Nanoparticles by Liquid Chemical Method and Their  Characterization

doi:10.3969/j.issn.1000-1093.2014.10.009

Abstract

Abstract: Aluminum nanoparticles are tried to be prepared by liquid chemical method to obtain their controlled microstructures. X-ray diffraction (XRD), field emission scanning electron microscope (FESEM) and energy dispersive spectrometer (EDS) are applied to characterize the aluminum nanoparticles. The effects of processing parameters including molar ratio of AlCl₃ to LiAlH₄, the adding amount of catalyst and the decomposition temperature on the structure, morphology and composition of the aluminum nanoparticles are studied in detail. The optimal preparation condition is achieved when the molar ratio of AlCl₃ to LiAlH₄ is 1∶6, the adding amount of catalyst is 0.04 mL, and the decomposition temperature is 110 ℃. The obtained aluminum is spherical-like with an average size of 50 nm and contains the minimum impurity elements Cl and Ti.
