摘要：

We report the first example of pentavalent-uranium silicate synthesized by a high-temperature, high-pressure hydrothermal method. The 3-D framework consists of four-membered single rings of corner-sharing SiO4 tetrahedra and 1-D UO4/1O2/2 chains. Magnetic susceptibility and XPS were measured to identify the valence state of uranium. Copyright © 2005 American Chemical Society.
