摘要：

The detailed study of U-O-Na and (U,Pu)-O-Na phase diagrams, corresponding to Na(3)MO(4) (M=U or U,Pu) composition, by high temperature neutron diffraction, room temperature X-ray diffraction and microcalorimetry, has revealed the existence of metastable compounds and the formation of a solid solution by dissolution of MO(2) in Na(3)MO(4). The existence of these new phases, with a disordered crystal structure, allows improved correlation with the previous results on the phase in equilibrium with MO(2) and Na.
