The mechanism of the precipitation and the composition of the precipitate which results from the reaction between uranyl nitrate and ammonia were studied by potentiometric, conductometric, and analytical methods. It is shown that the ammonium diuranate is not obtained as has been reponted in the literature. At the beginning a precipitate with the compoisition (NH/sub 4/)/sub 2/U/sub 7/O/sub 22/ is formed. However, after t he complete precipitation of the uranium, the initial precipitate is transformed into (NR/sub 4/)/sub 2/U/sub 4/O/ sub 13/). (tr-auth)
