From: Cr2+ solid solution in UO2 evidenced by advanced spectroscopy
a Oxygen defect content realised by deconvolution of Raman spectra of calcined material (errors derived from the standard deviation of 10 measurements); b U M4-edge HERFD XANES of calcined material. c Quantification of the U4+/5+ ratio in calcined powder determined from fitting of U M4-edge HERFD XANES data in b. d Oxygen defect content of sintered material realised by deconvolution of Raman spectra (errors derived from the standard deviation of 10 measurements). e U M4-edge HERFD XANES of sintered material; and (f) lattice parameter values for calcined powder and sintered material, as determined by p-XRD (errors derived from the lattice parameter refinement).
