Studies of the stability of the oxides schafarzikite, FeSb2O4, and tripuhyite, FeSbO4, have been undertaken to clarify the roles these secondary minerals may have in determining the dispersion of antimony in oxidizing environments. Solubilities were determined at 298.15 K in aqueous HNO3, and these data were used to calculate values of DGf at the same temperature. The derived DGf (s, 298.15 K) values for FeSb2O4 and FeSbO4 are 959.4 4.3 and 836.8 2.2 kJ mol , respectively. These results have… CONTINUE READING
