METHOD FOR SYNTHESIS OF HYDROXYAPATITE, AND HYDROXYAPATITE COMPLEX AND METHOD FOR PREPARING THE SAME

摘要

A method for synthesizing a hydroxyapatite (HAp), characterized in that it comprises dispersing a calcium hydroxide (H3PO4) powder in a aqueous solution of phosphoric acid (Ca(OH)2) to thereby prepare a raw material mixture slurry, and applying a shearing force and a compression force resulting from the centrifugal force of a mechanically rotating body to the resulting slurry for performing a mechanochemical grinding treatment of the raw material mixture and effecting a reaction between the above-mentioned phosphoric acid and calcium hydroxide components at ordinary temperature and under atmospheric pressure, to thereby obtain a microcrystal powder of hydroxyapatite. The present method can be used for producing a microcrystal powder of hydroxyapatite having a fine and uniform diameter directly, in a single process, with ease, with a short production time, at ordinary temperature and under atmospheric pressure.
