Conditions

Temperature
150 °C

Procedure

An aqueous zirconium sulfate solution and an aqueous ammonium dihydrogenphosphate solution were mixed at a ratio of zirconium and phosphorus of 2:3 to produce a precipitate. Then, pH of the resulting slurry was adjusted to 2 with an aqueous sodium hydroxide solution, followed by heating at 150° C. for 24 hours in the hydrothermal state to obtain crystalline zirconium phosphate.
