ABSTRACT:
Zirconium phosphate particles are synthesized by providing a solution of zirconium oxychloride in an aqueous solvent, adding at least one oxygen-containing additive to the solution, the oxygen-containing additive being selected to form a complex with zirconium ions in the solution of zirconium oxychloride and thereby reduce hydration of the zirconium ions, and combining this solution with phosphoric acid or a phosphoric acid salt to obtain zirconium phosphate particles by sol gel precipitation.
