Abstract
Uranium chloride phosphate tetrahydrate UClPO4. 4H(2)O was obtained by mixing uranium (IV) hydrochloric solution and concentrated phosphoric acid [1]. From crystal structure studies its formula was determined a s dihydrate [2]. Using the same method, i.e. starring From uranium (IV ) hydrobromic solution and H3PO4, two crystal forms of a new compound, uranium bromide phosphate UBrPO4. 2H(2)O were synthesized. Their XRD patterns, W-visible and infrared spectra are presented in this paper. The hydrolysis process of the chloride and bromide phosphates leads to the amorphous uranium hydroxide phosphate U(OH)PO4. 6H(2)O. (C) Acade mie des sciences/Elsevier, Paris.
