摘要：

Pure crystalline compounds (MU3O10)-U-II n H2O (MII = Ca, Sr) and BaU2O7 3 H2O were obtained by reactions of synthetic schoepite (UO3 2.25 H2O) with aqueous solutions of calcium, strontium, and barium nitrates under hydrothermal conditions at 200 degrees C and pH 78. Their structure, dehydration, and thermal decomposition were studied by chemical analysis, X-ray fluorescence spectrometry, X-ray powder diffraction, IR spectroscopy, and thermogravimetric analysis.
