  • Phosphate Minerals an overview ScienceDirect Topics

    Iron and aluminumphosphate minerals are not common in soils. For the soil samples reported in Fig. 11.13 Fephosphates (strengite or noncrystalline Fe phosphate) were found as a minor component (1030% of P t) in only two of the five acid soil samples. No Alphosphates were detected from P Kedge XANES analysis. Ajiboye et al. (2008) reported strengite (9% and 28% of P t) in 2 of 10

  • Phosphate mineral Wikipedia

    Phosphate minerals contain the tetrahedrally coordinated phosphate (PO 4 3) anion along sometimes with arsenate (AsO 4 3) and vanadate (VO 4 3) substitutions. Chlorine (Cl ) fluorine (F ) and hydroxide (OH ) anions that also fit into the crystal structure.. The phosphate class of minerals is a large and diverse group however only a few species are relatively common.

  • Spectra from a study of the basic copper phosphate

    The molecular structures of the basic copper phosphate minerals pseudomalachite libethenite and cornetite were studied using a combination of infrared emission spectroscopy infrared absorption and Raman spectroscopy. Infrared emission spectra of these minerals were obtained over the temperature range 100 to 1000 °C. The infrared spectra of the three minerals are different in line with
