Summary:

An investigation into the nature and solubility of a stable solid phase formed by a trivalent actinide, /sup 243/Am/sup 3 +/, in dilute aqueous carbonate solutions was conducted. The compound exhibited an x-ray powder diffraction pattern which was nearly identical to that reported for NdOHCO/sub 3/ - type A. The pattern could be indexed in the orthorhombic system with unit cell parameters a = 4.958, b = 8.487, and c = 7.215 A. The steady-state solubility of the compound was determined from the results of both dissolution and precipitation experiments. The average solubility product quotient for 0.1M ionic strength, 25 +- 1/sup 0/C and 1 atmosphere pressure was found to be 583 +- 206. The solubility product constant for zero ionic strength was estimated to be 335 +- 120. 22 references, 3 tables.
