; ; ;
The solubility products of synthetic uranyl phosphates (H-autunite, Ga-autunite, and torbernite), as well as the Gibbs free energy of these minerals, were determined under standard conditions. The principal modes of origin of natural uranyl phosphates are outlined. The solubility of Ga-autunite and torbernite depended largely on pH. H-autunite formed only in an ultra-acidic medium.
