POUDRE D'UN ALLIAGE A BASE D'URANIUM ET DE MOLYBDENE EN PHASE GAMMA-METASTABLE, COMPOSITION DE POUDRES COMPRENANT CETTE POUDRE, ET UTILISATIONS DESDITES POUDRE ET COMPOSITION

摘要

The subject of the invention is a powder of an alloy comprising uranium and molybdenum in ?-metastable phase, a composition of powders comprising this powder and also the uses of said alloy powder and of said composition of powders. The alloy powder comprising uranium and molybdenum in ?-metastable phase according to the invention is formed of particles comprising a core which consists of said alloy and which is coated with a layer of alumina located in contact with this core. Applications: manufacture of nuclear fuel elements and, in particular, of fuel elements for experimental nuclear reactors; manufacture of targets intended for the production of radioelements, of use in particular for medical imaging such as technetium 99m.
