실험 절차

Basically, according to the present invention, an acidic calcium phosphate solution is reacted with a calcium hydroxide solution, with both solutions near saturation when combined, so as to obtain an amorphous hydroxylapatite precipitate without undesired side reactions. After separation and drying, hydroxylapatite precipitate is sintered at 700°-1100°C. for about 5-30 minutes to obtain the desired ceramic hydroxylapatite material.
