Abstract
Monocarbonates and dicarbonates of Npsup((4)), Pusup((5)), and Amsup((5)) with cations Na/sup +/, K/sup +/, and NH/sub 4//sup +/ have been synthesized. The compounds have the following composition: KXO/sub 2/CO/sub 3/xnH/sub 2/O and NH/sub 4/NpO/sub 2/CO/sub 3/xnH/sub 3/O, where x=Np, Pu, or Am; n (<=) 2. They have been studied chemically, thermogravimetrically and by X-ray diffraction method. It has been established that monocarbonates have a hexagonal structure and complex composition corresponding to the formula MXO/sub 2/CO/sub 3/xnH/sub 2/O with a zeolite nature of water molecules. Thermal stability of dicarbonates within the temperature range 20-500/sup 0/C has been studied. An effect of hydration and dehydration on a change in the lattice parameters has been investigated. The data are given on separation, identification, and properties of some sodium carbonatoneptunailates which differ in their physico-chemical properties from other monocarbonates. The main distinctive feature is th eir ability to lose and accept water molecules readily, forming different hydrate forms.
