Abstract:
Zirconium phosphate particles are synthesized by providing a solution of zirconium oxychloride in an aqueous solvent, adding at least one low molecular weight, oxygen containing, monofunctional, organic additive to the solution, and combining this solution with heated phosphoric acid or a phosphoric acid salt to obtain zirconium phosphate particles by sol gel precipitation.
