Mode opératoire

0.2 mol of zirconium oxychloride octahydrate and 0.05 mol of ammonium chloride were dissolved in 300 ml of deionized water, and then 0.3 mol of phosphoric acid was added thereto under stirring. A 20% aqueous sodium hydroxide solution was added to the solution to adjust the pH to 3.6, and then the resulting precipitates were washed well, and calcined at 900° C. By pulverizing a bulky product obtained by the calcination, a zirconium phosphate compound was synthesized.
