Mechanochemical synthesis of complex zirconium phosphates

摘要

Cation- and anion-substituted zirconium phosphates of X{sub}kZr{sub}m(PO{sub}4){sub}(n-y)Y composition, where X ＝Na{sup}+, La{sup}(3+), NH{sub}4{sup}+, Y ＝F{sup}-, WO{sub}4{sup}(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℃. The interaction between components was studied by XRD, EXAFS, FT-IR, [(31){sup left}P-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.
