Surface area and morphological characterizations of nuclear materials may aid in the identification of interdicted materials for nuclear forensic purposes. Variability in the synthetic method used, including fluctuations in temperature, reaction stirring rate, rate of addition of reagents, and concentration of uranium starting materials may lead to differences in the morphology of the products. Ammonium diuranate (ADU) and a series of uranium oxides were synthesized using a variety of routes and characterized using powder X-ray diffraction (pXRD), scanning electron microscope (SEM) imaging, image analysis using Morphological Analysis for Material Attribution (MAMA) software, and surface area analysis using the BET method. These characterization methods identified differences in morphology, which were then correlated to the synthetic method.<br/>
