Curium

Electrochemical processing in molten salts – a nuclear perspective

“…152 Moreover, 244 Cm demonstrates remarkable incandescence, yielding 122 W g −1 , on the other hand, 238 Pu, which is more readily available, has been preferred in applications requiring this attribute. 153 The third most commonly studied isotope, 248 Cm, has also been used as an enriched target for the production of the transfermium nuclides (elements with atomic numbers greater than one hundred). 154 Curium has a much lower volatility than americium.…”

Separation of americium from highly active raffinates by an innovative variant of the AmSel process based on the ionic liquid Aliquat-336 nitrate

“…27 Despite the benefits of such a strategy, the separation of americium from curium is a challenge as both elements usually occur as trivalent cations with similar ionic radii (0.98 Å for Am 3+ and 0.97 Å for Cm 3+ ). 28–30 This led to the development of the EXAm process, which evolved from the DIAMEX-SANEX process. 31–34 The Am/Cm separation is achieved by selective extraction of Am with N , N ′-dimethyl, N , N ′-dioctylhexylethoxymalonamide (DMDOHEMA) and HDEHP in a hydrogenated tetrapropylene (HTP) diluent.…”

Periodic trends in trivalent actinide halides, phosphates, and arsenates

“…97 Curium trihalides are reported in the literature. 1,16,90,94,98,99 Their synthesis, characterization, and crystal structures are studied and discussed in the work of Asprey et al 94 In the work of Moll et al , the presence of Cm( iii ) in phosphoric acid solutions, as Cm( iii ) phosphate species viz ., CmHPO 4 + and CmH 2 PO 4 2+ , has been discussed. 100 Trihalides (except astatides) and phosphates of berkelium are reported in the literature.…”
