Figure 2: X-ray diffractograms of synthetic HAp and bovine bone. Qualitative identification of the crystalline phase established by comparison between reflections of the profile measured with diffraction profile reflections, reported by the International Center for Diffraction Data (ICDD) (powder diffraction file) using search-match software illustrates (a) hydroxyapatite components synthesized by the wet technique and (b) bovine bone analysis after treatment for cell seeding.
