A mixture of metavivianite, vivianite, and spheniscidite was obtained from an aqueous solution of FeSO4•7H2O and (NH4)2HPO4 at temperatures between 50 and 60 °C. The oxidation sequence of partially oxidized vivianite toward santabarbaraite or a solid solution between β–Fe2 (PO4)O and Fe4 (PO4)3 (OH) 3, without passing through metavivianite, was also demonstrated.
