Title: Effect of pH on the properties of ammonium uranate precipitated with gaseous ammonia.
Authors: Woolfrey, JL
Issue Date: Nov-1976
Publisher: Australian Nuclear Science and Technology Organisation
Abstract: Ammonium uranate (AU) powders were precipitated from a uranyl nitrate solution using gaseous ammonia to determine the effect of pH of precipitation on their composition and morphology. Increasing pH of precipitation increased the ammonia and nitrate contents and the specific surface area but decreased the crystallite size of the AU powders. The specific surface area was also increased by increasing the ammonia content of the powder. The composition and morphology of the powders were similar to those reported in the literature for AU precipitated with NH4OH.
