실험 절차

Generally, the present invention provides a process for obtaining hydroxylapatite by blending dilute aqueous solutions, preferably solutions that are near saturation, of monobasic calcium phosphate (monocal) and calcium hydroxide, followed by separation (e.g. centrifugation), drying, and sintering of the precipitate at 700-1100°C. for about 5-30 minutes to obtain hydroxylapatite having close to the theoretical Ca/P ratio. Thus, in one form of the present invention, a dilute aqueous solution of monobasic calcium phosphate (monocal) is brought into contact with a dilute aqueous solution of calcium hydroxide, in carefully metered proportions, to obtain the amorphous hydroxylapatite precipitate.
