Sažetak

The spontaneous precipitation in the systems U02(N03)2-
-MOH-HaP04--H20 and U02(N03)2-MNOa-H3P04- H20 (M =
= Li, Na, K, Rb, Cs) is examined. The formation of alkaline-
uranyl(2+) phosphates polyhydrates is detected: M[U02P04] ·
· n H20 (n = 4 for M = Li, n = 3 for M = Na, K, Rb and n = 2.5
for M =Cs).
The X-ray powder patterns of these compounds are determined
and compared with that of H30[U02P04] · 3 H20. A close structural
relation within this series is observed. The size of the alkaline
ionic species in the particular compound affects the content of
crystalline water in the unit cell.
