Cs2K(UO)2Si4O12: a mixed-valence uranium(IV, V) silicate |
2009/11/16 |
The first mixed-valence uranium(IV,V) silicate is synthesized under high-temperature, high-pressure hydrothermal conditions. The structure contains chains of corner-sharing UIV,VO6 octahedra which are interconnected by Si4O12 four-membered rings to form a 3-D framework. XPS and XANES spectra were measured to identify the valence state of uranium. The research was conducted at the NSRRC beamline BL01C1.
