Resumo

The interaction of hydrated uranium(VI) oxide UO₃·2.25H₂O (schoepite) with an aqueous solution of rubidium hydroxide in an autoclave at 100°C has yielded rubidium uranate Rb₂(UO₂)₆O₃(OH)₈·6H₂O. Composition and structure of the obtained compound have been determined by chemical analysis, IR spectroscopy, X-ray diffraction, and differential thermal analysis. The processes of its dehydration and thermal decomposition have been studied.
