The phases formed by heating Mn(II) and Zn(II) exchanged α-zirconium phosphate Academic Article uri icon


  • The phases formed upon heating α-zirconium phosphate, Zr(HPO4)2·H2O, loaded to different levels of Mn(II) and Zn(II) were determined by a combination of thermal and X-ray powder methods. The fully exchanged phases, ZrM(PO4)2·4H2O lose water stepwise at progressively higher temperatures until anhydrous. Above 500°C the X-ray pattern indicates a triphosphate-like phase of the type M0.5Zr2(PO4)3 is formed. At lower loadings, solid solutions with relatively broad composition regions are observed. The data are summarized in phase diagrams which, however, are not equilibrium diagrams. © 1983.
