Preparation of uranium by electrolysis in chloride melt

The uranium deposits were prepared by electrolysis in a fused chloride melt. Whatever the electrolysis conditions, the deposit morphology was dendritic. The influence of the parameters current density, melt temperature and electrolyte concentration on the morphology was investigated using an optimal design. Our results show that increasing the temperature makes the coatings more compact. The dendritic morphology is attributed to transport phenomena (diffusion, convection, migration) promoted by the cation discharge at the substrate-coating interface.
