実験手順
Brushite was prepared in the same manner as in Example 1 except that 1 l of an aqueous calcium chloride solution of 0.5 mol/l in concentration and 1 l of an aqueous disodium phosphate solution of 0.5 mol/l in concentration were used and reaction temperature was room temperature. Then, at 95° C., 300 ml of an aqueous sodium hydroxide solution of 1 mol/l in concentration was added to the resulting brushite over a period of 1 hour to obtain hydroxylapatite in the form of platy crystal [hereinafter referred to as "hydroxylapatite (H)"].
