ChemInform Abstract: High‐Temperature, High‐Pressure Hydrothermal Synthesis and Characterization of a Salt‐Inclusion Mixed‐Valence Uranium(V,VI) Silicate: [Na9F2] [(UVO2)(UVIO2)2 (Si2O7)2].

Abstract

Abstract The title compound is hydrothermally synthesized from an aqueous mixture of UO 3 , NaOH, NaF, Na 2 HPO 4 , and Na 2 SiO 3 in a molar ratio of Na:F:U:P:Si = 39:5:1:2:10 (autoclave, 160 MPa, 585 °C, 2 d, 71% yield).
