The purpose of this study is to examine synthesis approach of OAp and properties of synthesized OAp. OAp was synthesized by the wet method with 30%H_2O_2 solution, and synthesized OAp characterized by using XRD, IR, ESR and TG-DTA analysis, and antimicrobial activity and adsorptive activity of OAp were measured. It was confirmed by XRD and FT-IR analysis that synthesized OAp was Calo(PO_4)_6O. Furthermore, the ESR spectra of OAp containing reactive oxygen radicals were observed. Although reactive oxygen radicals disappeared at the high temperature, it existed comparatively with stability in the apatite matrix at the low temperature heating, Thus, these results suggest that OAp containing reactive oxygen radicals serve as an antimicrobial material.
