実験手順

Oxalic acid and phosphoric acid are added, in this order, to an aqueous solution of zirconium oxynitrate and sodium nitrate, with stirring. The mixture is adjusted to pH 3.5 with an aqueous sodium hydroxide solution and then refluxed under heating for 78 hours. The resulting precipitate is collected by filtration, water-washed, dried and disintegrated to obtain a zirconium phosphate [NaZr2 (PO4)3 ] having a network structure.
