From Nd(III) and Pu(III) Oxalates to Oxides: Influence of Nitrilotris(methylenephosphonic acid) on Chemical Composition, Structure, and Morphology

Neodymium oxalate structure and morphology were modified by adding a phosphonate, NTMP, during the oxalic precipitation step. Spherical agglomerates of neodymium oxalate Nd2(C2O4)3(H2O)6·12H2O composed of thin hexagonal rods were precipitated instead of decahydrated oxalate Nd2(C2O4)3(H2O)6·4H2O with rod-like particles usually obtained in the absence of additive. Despite some differences in the complexation with NTMP and complexity from redox, the use of NTMP was successfully transposed to the plutonium system. Spherical agglomerates of plutonium(III) oxalate were so obtained, leading to spherical agglomerates of PuO2 after thermal treatment.

Synthesis and thermal decomposition of mixed Gd-Nd oxalates

Several (Gd1-xNdx)2[C2O 4]3?nH2O samples (0≤x≤1) were prepared by a coprecipitation method: the precipitation is quantitative and all the samples are homogeneous in stoichiometry. XRD analyses have shown that a complete solid solution is formed over the whole range of compositions. The dried Gd rich oxalates have initially a low water content which gradually increases with the Nd content. All the oxalates decompose in O2 around 700°C either into a single mixed oxide or in a mixture of oxides through several steps, which can be ascribed to the loss of water and CO 2.
