Abstract
The present invention is a process for easily producing a hexagonal zirconium phosphate powder having excellent dispersibility and a specific particle size distribution by the use as a starting material of a zirconium carbonate powder for which a specific particle size is easily obtainable. A hexagonal zirconium phosphate powder having a specific particle size distribution and high crystallinity can be produced by making zirconium carbonate be present in an aqueous solution containing phosphate ion and at least one of ion selected from an alkali metal ion, an alkaline earth metal ion, and ammonium ion, aging by a wet method, and then heating under dry conditions.
