Abstract:
Phosphosiderite from Atacama (Chile) was studied by X-ray powder diffraction, Mössbauer spectroscopy and chemical analysis. The arsenic content reaches 9 As2O5 wt%. The averaged formula obtained is [Fe0.96Al0.04)[(PO4)0.94(AsO4)0.06]·2.04H2O. Isomorphic substitution As → P in the tetrahedral positions was established. The parameters of the monoclinic cell are a = 5.3258(6) Å, b = 9.8003(11) Å, c = 8.7116(9) Å, β = 90.64(1)°.
