反応手順
The present invention also provides methods of synthesizing hydroxyapatite granules having homogenous cellular structures. A slurry of hydroxyapatite is prepared by dissolving calcium hydroxide or calcium nitrate in a saturated ammonium hydroxide solution. The ammonium hydroxide solution is pH 11 or greater. Phosphoric acid or ammonium phosphate is then added to this solution, preferably in a dropwise manner to produce a calcium-phosphate ratio of approximately 1.5 to 1.7.
