It is shown that freshly precipitated Pu(IV) oxalate loses three molecules of water. After 3 to 4 days an additional 1.5 to 2.7% of CO + CO/sub 2/ precipitates due to the disintegration of oxalate under Pu alpha irradiation at 110 deg C. Simultaneously, partial recovery of Pu(III) takes place. Two additional water molecules and 13% CO + CO/sub 2/ precipitate at 170 to 200 deg C wtth the recovery of Pu(III) in the inltial Pu/sub 2/(C/sub 2/O/sub 4/)H/sub 2/O; at 380 deg C the oxalate transforms into PuO/sub 2/. At 140 deg C the oxalate of Pu(III) completely dehydrates and at 250 deg C in the atmosphere it transforms into PuO/sub 2/. In inert media at 330 deg C oxalate decomposes forming carbonate oxalate. At 460 deg C the carbonate oxalate decomposes and Pu(III) oxidizes into Pu(IV) with the formation of dioxide. (tr-auth)
