The storage of spent nuclear fuels for long periods of time in geological repositories is one
proposed solution to the stewardship of legacy, current and future nuclear waste. Recent …

Volume 38 of Reviews in Mineralogy provides detailed reviews of various aspects of the
mineralogy and geochemistry of uranium. We have attempted to produce a volume that …

In crystal structures of minerals and synthetic compounds that contain hexavalent U, the U6+
cation is almost always present as part of the stable, approximately linear uranyl ion: U022+ …

Raman and infrared spectra of five uranyl oxyhydroxide hydrates, becquerelite, billietite,
curite, schoepite and vandendriesscheite, are reported. The observed bands are attributed …

Fleischer 60, 61 has shown that more than 160 species can be identified that contain
uranium as an essential element. In many additional species uranium is known to play a …

Uranyl minerals form as a result of the oxidation and alteration of uraninite, UO2+ x. These
uranyl phases are also important alteration products of the corrosion of UO2 in used nuclear …

The related crystal structures of three uranyl oxide hydrate minerals, becquerelite, billietite,
and protasite, have been determined by single-crystal X-ray diffraction. The chemical …

The crystal structures and chemical compositions of uranyl-oxysalt minerals (primarily with
sheet structural units) are interpreted in terms of the binary representation–bond-valence …

Raman spectra of liquid and gaseous zirconium tetrachloride and of molten ZrCl4–CsCl
mixtures have been measured. Changes of the relative Raman intensities in the vapor …

The structure of vandendriesscheite, Z= 8, Pb1. 57 [(UO2) 10O6 (OH) 11](H2O) 11,
orthorhombic, a= 14.1165 (6), b= 41.378 (2), c= 14.5347 (6) Å, V= 8490 Å3, space group …
