The AXO4 monazite-type compounds form an extended family that is described in this
review in terms of field of stability versus composition. All the substitution possibilities on the …

Available publications on crystalline materials used to immobilize HLW and actinides have
been analyzed. Select compounds and solid solutions covered in this paper are phosphates …

Potential vs. pH or Eh–pH diagrams for the systems Th–, La–, Nd–, Ce–,(PO4)–(SO4)–H2O
at 25° C were generated using the HSC5. 0 software. The thermodynamic data available in …

The conditioning of radioactive waste from nuclear power plants and in some countries even
of weapons plutonium is an important issue for science and society. Therefore the research …

Hydrated rhabdophane with a general formula REEPO4· n H2O (REE: La→ Dy) has been
always considered to crystallize in the hexagonal system. A recent re-examination of this …

This paper focuses on major phosphate-based ceramic materials relevant for the
immobilisation of Pu, minor actinides, fission and activation products. Key points addressed …

Rare earth elements (REE) are critical elements found in monazite, xenotime, and hydrated
REE phosphates which typically form in hydrothermal mineral deposits. Accurate predictions …

A systematic study of the solubility of the rhabdophanes LnPO4· 0.667 H2O (Ln= La–Dy)
was performed through oversaturation and undersaturation experiments at different …

Rhabdophane is an important permeable reactive barrier to enrich radionuclides from
groundwater and has been envisaged to host radionuclides in the backend of the nuclear …

Bastnäsites (LnCO 3 (F, OH)) are a group of common rare earth elements (REE)-bearing
minerals and are one of the primary global sources of REE. Due to the chemical similarities …
