Phase formation along the PO34/Zr = 1.5 Section of the ZrO(NO3)2-H3PO4-CsF-H 2O system
The phase formation in the system ZrO(NO3)2 H 3PO4 CsF H2O was studied along the section at the molar ratios PO^/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 2O, were isolated, and the known phosphate zirconate CsZr 2(PO4)3 was obtained for the first time by calcining acidic fluorophosphate zirconate.
