| Abstract: | Cation- and anion-substituted zirconium phosphates of X
kZr
m
(PO4)
n–y
Y composition, where X = Na+, La3+, NH4
+, Y = F–, WO4
2–, 1/3 < k < 2, 2 < m < 4, 3 < n < 6 were synthesized by the procedure, including mechanical activation of the starting salts mixture followed by annealing at 300–900°C. The interaction between components was studied by XRD, EXAFS, FT–IR, 31P-MAS] NMR. The possibility of synthesizing nonstoichiometric compounds is demonstrated and prospects for application of the mechanochemical method for synthesis of complex zirconium phosphates are outlined. |
