الإجراء التجريبي

0.272 mol of zirconium oxychloride octahydrate containing 1.2% of hafnium was dissolved in 850 ml of deionized water, and thereafter, 0.788 mol of oxalic acid dihydrate was dissolved therein. 0.57 mol of phosphoric acid was added to the solution under stirring. The solution was stirred and refluxed for 8 hours. After cooling, the obtained precipitate was well washed with water, and thereafter dried at 105° C. to obtain a zirconium phosphate. As a result of measurement of the obtained zirconium phosphate, it was confirmed to be a layered zirconium phosphate.
