- Summary:
- Uranium trioxide (UO₃) was characterized using a variety of techniques to better understand its physical properties. Scanning electron microscope (SEM) images were collected to examine particle morphology, which consisted of semi-spherical particles that tended to agglomerate before sonication. Particle size analysis revealed a singular mode distribution with a mean particle size of 43.0 {micro}m. After sonication a bimodal distribution was produced with peak particle sizes at 0.226 {micro}m and 9.43 {micro}m. The O/U ratio was measured to be 3.09 by Cameco in 2009, by gravimetric analysis. X-ray diffraction (XRD) showed that the sample was mostly γ-UO₃ (87.1%) with a small amount of UO₃ · 0.80 H₂O (12.9%). Bulk and tap densities were determined to be 3.678 ± 0.2 and 4.81 ± 0.2 g/cm³, respectively (crystalline density is 7.3 g/cm³). The stoichiometry was measured to be 2.99 in 2012.
