Uranophane - Wikipedia
Uranophane (Ca(U O 2) 2 (SiO 3 OH) 2 ·5H 2 O), also known as uranotile, is a rare calcium uranium silicate hydrate mineral that forms from the oxidation of other uranium-bearing minerals. It has a yellow color and is radioactive .

Spectral variability of the uranyl silicates uranophane-α and ...
2022年12月2日 · We show evidence that variable amounts of uranophane-β phase embedded in uranophane-α are possibly at the origin of this spectral signature. Growth of those uranophane-β clusters might be induced by defects in the uranophane-α lattice and further promoted by the polymorphism of uranophane.

Characterisation of Uranophane and Boltwoodite by Raman, …
2022年3月1日 · Uranophane and boltwoodite are potential alteration products of spent nuclear fuel. Mineral specimens were characterised LIBS, Raman and luminescence spectroscopy. Luminescence emission peak positions can discriminate between uranophane polymorphs. First reported luminescence excitation spectra for uranophane and boltwoodite.
