Phase formation along the PO 43- /Zr = 1.5 section of the ZrO(NO3)2-H3PO4-CsF-H2O system

The phase formation in the system ZrO(NO3)2-H3PO4-CsF-H2O was studied along the section at the molar ratios PO43-/Zr = 1.5 and CsF/Zr = 2-5 at a ZrO2 concentration in the initial solution of 2--5 wt %. New fluorophosphate zirconates, CsH2Zr2F2(PO4)3 ? 1.5H2O and two modifications of CsZrF2PO4 ? 0.5H...

Summary:The phase formation in the system ZrO(NO3)2-H3PO4-CsF-H2O was studied along the section at the molar ratios PO43-/Zr = 1.5 and CsF/Zr = 2-5 at a ZrO2 concentration in the initial solution of 2--5 wt %. New fluorophosphate zirconates, CsH2Zr2F2(PO4)3 ? 1.5H2O and two modifications of CsZrF2PO4 ? 0.5H2O, were isolated, and the known phosphate zirconate CsZr2(PO4)3 was obtained for the first time by calcining acidic fluorophosphate zirconate.
