Obtained nanoparticles were identified as magnetite (Fe_3O_4) by XRD measurement. It was found that obtained magnetite nanoparticles have small sizes (about 10.7 ±2.9 nm in diameter) and spherical shape by TEM observations. In reverse precipitation method, the dropping conditions of aqueous FeSO_4 solution affect on the sizes and uniformity of the products., text, Nagasaki Symposium on Nano-Dynamics 2008 (NSND2008) 平成20年1月29日(火)於長崎大学 Poster Presentation, Nagasaki Symposium on Nano-Dynamics 2008 (NSND2008), pp.85-86}, pages = {85--86}, title = {Sonochemical preparation of magnetite nanoparticles by reverse precipitation method}, year = {2008} }
