Synthesis of rutherfordine and its stability in water and alkaline solutions

Autor: Vochten, Renaud, Blaton, N.

Publikováno v: Neues Jahrbuch für Mineralogie: Monatshefte

Rutherfordine, UO2CO3, was synthetically prepared from schoepite, UO2(OH)(2). 2H(2)O and solid CO2 at 100 degrees C. Synthetic rutherfordine was transformed into compreignacite, K-2(UO2)(6)O-4(OH)(6) . 8H(2)O, its sodium analogue and UO3 . 0.8H(2)O.
