| Zusammenfassung: | To provide a method for producing hydroxyapatite for a biocompatible material having excellent biocompatibility and bioactivity.SOLUTION: A method for producing the hydroxyapatite comprises the steps of: obtaining a hydroxyapatite by firing bones of salmonid fish at a temperature in the range of 300 to 1200°C; and pulverizing the hydroxyapatite so as to have an average particle diameter in the range of 2 to 14 μm and a specific surface area in the range of 1 to 5 m2/g.SELECTED DRAWING: Figure 1
【課題】優れた生体親和性及び生体活性を備える生体親和性材料用ハイドロキシアパタイトの製造方法を提供する。【解決手段】サケ科の魚類の骨を３００〜１２００℃の範囲の温度で焼成してハイドロキシアパタイトを得る工程と、該ハイドロキシアパタイトを２〜１４μｍの範囲の平均粒子径と、１〜５ｍ２／ｇの範囲の比表面積とを備えるように粉砕する工程とを備える。【選択図】 図１ |
