Abstract
A process is described for synthesizing a mixed peroxide or hydroxo-peroxide of an actinyl and at least one cation X, wherein the actinyl is a uranyl or neptunyl and the at least one cation Xis a di-, tri- or tetra-charged metal cation. This process includes the reaction in a solvent of a salt of the at least one cation Xwith a compound Cselected from mixed peroxides and hydroxo-peroxides of the actinyl and of at least one singly charged cation X, whereby compound Cis converted to the peroxide or hydroxo-peroxide by replacement of the at least one cation Xby said at least one cation X. Also disclosed is a process for synthesizing a mixed oxide of an actinide selected from uranium and neptunium, and of at least one metal able to form a di-, tri- or tetra-charged cation, which implements the preceding synthesis process. The disclosure further relates to a mixed peroxide or hydroxo-peroxide of an actinyl and of at least one di-, tri- or tetra-charged metal cation, and the use thereof for the preparation of a mixed oxide of an actinide and of at least this metal.
