摘要：

Rice ball shaped alpha-Fe2O3 microstructures have been synthesized using a single-step Fe(NO3)(3) solution calcination route without the assistance of any other additions. A series of techniques, including XRD, XPS, FE-SEM and DLS ones, were used to characterize the product. Thermogravimetric (TG) analysis provided insight into the decomposition process of the Fe(NO3)(3) precursor. A possible growth mechanism of the rice ball shaped alpha-Fe2O3 microstructures was explained. (C) 2009 Elsevier Ltd. All rights reserved.
