ABSTRACT:
In one embodiment of the present invention, a process for manufacturing at least one particulate material is disclosed, the process including the following consecutive steps of: a) introducing into a vibrating grinder at least two powders each comprising UO2, provided by two different synthesis routes and of close specific surface area; b) shaking the powders into the grinder so as to form a particulate material, the grinding intensity being sufficient to break up the agglomerates and the aggregates in the powders without at the same time breaking up the crystallites in the powders, and the grinding energy being such that all of the agglomerates and aggregates are destroyed. One embodiment of the present invention also concerns a particulate material obtained by this process.
