Resumo
Sodium and potassium uranates with the compositions M2[(UO2)6O4(OH)6] · 8Н2 (M = Na, K) have been synthesized by reacting schoepite (UO3 · 2.25H2O) with aqueous sodium hydroxide and potassium hydroxide solutions (pH 10–12) under hydrothermal conditions at 100°C for 15 days. Chemical analysis, X-ray diffraction, IR spectroscopy, and thermogravimetry data demonstrate that these compounds are perfect compositional and crystallographic analogs.
