The possible isomorphous substitution of calcium by uranium in the apatite lattice was investigated. Apatite, prepared by crystallization from a melted solvent with both tetravalent and hexavalent uranium present, contains no more than 0.05% uranium, which is present as submicrcscopic inclusions. By suspending apatite in water solutions containing U/sup 4+/ or (UO/sub 2)/sup 2+/, uranium is precipitated by phosphoric ions passing into solution from the mineral, and the apatite crystal is covered with a patina of uranium phosphates. The possible substitution of calcium by uranium in the apatite lattice was not confirmed. (auth)
