Abstract

Hydroxyapatite powders (HAp; Ca₁₀(PO₄) ₆(OH)₂) hybridized with 0-5 mass % Al₂O ₃ were prepared from calcium hydroxide and di-aminonium hydrogenphosphate by a wet chemical synthesis. Ethylacetoacetate Aluminum Diisopropoxide (Al(OC₃H₇)₂(C₆H ₉O₃)) was used as a source for aluminum oxide. The obtained powders were characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) specific surface area measurement, and magic angle spinning-nuclear magnetic resonance spectroscopy (MAS-NMR). The X-ray diffraction patterns showed no Al₂O₃-peaks irrespective of Al₂O₃ content, suggesting that the Al₂O ₃-hybridized HAp powders were single phase. The Al₂O ₃-hybridized HAp powder had larger specific surface area. According to MAS-NMR analysis, it was considered that the aluminum element existed as aluminum oxide, it was not substituted for the Ca²⁺, PO ₄^3-, or OH^- ions.
