Synthesis and study of uranosilicates of the uranophane-kasolite group
Tóm tắt
A series of uranosilicates of alkali (Li, Na, K, Rb, Cs, NH4), alkaline-earth (Mg, Ca, Sr, Ba), and rare-earth (Y, La, Ln) elements were prepared by precipitation from a solution under hydrothermal conditions. The composition and structure of the compounds were examined by X-ray diffraction analysis, IR spectroscopy, and thermal analysis. It was established that these compounds belong to the uranophane Mk[HSiUO6]
