Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for synthesizing zirconium phosphate particles by an improved sol-gel method which can be performed on a production scale and in which the formation of soft gel particles is avoided and/or the agglomeration of zirconium phosphate gel particles is avoided.SOLUTION: There is provided a method for synthesizing zirconium phosphate particles which comprises: a step of obtaining a zirconium oxychloride solution in an aqueous solvent; a step of adding at least one oxygen-containing additive to the solution (the oxygen-containing additive is selected to form a complex with zirconium ions in the zirconium oxychloride solution and thus the hydration reaction of the zirconium ions is reduced); and a step of mixing the solution and phosphoric acid or a phosphoric acid salt to obtain zirconium phosphate particles by sol-gel precipitation.
