The kinetics of hydrogen reduction of UO3 and U3O8 derived from ammonium diuranate

The preparation of UO2 powder: Effect of ammonium uranate properties

Thermal decomposition of ammonium uranate—an IR study

Films containing uranium obtained by electrodeposition and used in alpha spectroscopic analysis were characterized by absorption spectroscopy, Raman spectroscopy, X-ray diffraction analysis and thermoanalysis. The electrodeposition method produced thin, adherent films with a yield near 100%. The analysis indicated that these films contained uranyl groups isolated or attached to other uranyl groups by oxygen bridges. Hydration water, hydroxyl groups linked by hydrogen bonds and ammonium radicals were also present. According to the X-ray diffraction analysis the films showed low crystallinity, characteristic to electrodeposited materials. The results of the thermogravimetric and differential thermal analysis did not correspond to any known pattern.
