Comparison of XRD, XANES and TGA methods to assess the O/M ratio of Th0.60Am0.40O2−x

The mixed oxide Th0.60Am0.40O2−x has been synthesized and characterized after reductive and oxidative thermal treatments. Both materials are monophasic solid solutions. The determination of O/M ratio was achieved combining XRD, XANES and TGA, showing the consistence between the three methods. This study represents a further step in our investigation of the Th-Am-O system and improves it comprehension.
