Procedure

0.67 moles of zirconium basic carbonate (3ZrO2.CO2.xH2O) containing 2.1% hafnium wherein a median particle size thereof was 18 μm and particles with a particle size of 0.8 μm to 50 μm were present at 100% on a volume basis of the total particles were suspended in 300 ml of deionized water, and 0.27 moles of phosphoric acid were added thereto with stirring. A 20% aqueous solution containing 0.07 moles of potassium hydroxide was further added thereto, followed by heating and aging for 2 hours at 98° C. Then, the resulting solid was not washed and the solid was taken out and dried at 120° C. for 3 hours.
