Summary:To provide HAP particles having high crystallinity, and a novel HAP production method that makes it possible to produce such HAP.SOLUTION: HAP particles disclosed herein have FOM of 0.700 or less in X-ray diffraction measurement. A method for producing HAP particles disclosed herein includes the step of reacting a calcium source and a phosphoric acid source in an aqueous solution with a pH of more than 9.0 and 13.5 or less by chemical sedimentation.SELECTED DRAWING: Figure 1 【課題】 本開示は、高い結晶性を有するＨＡＰ粒子を提供すること、及びそのようなＨＡＰを製造できる、ＨＡＰの新規な製造方法を提供することを目的とする。【解決手段】 本開示のＨＡＰ粒子は、Ｘ線回折測定によって得られるＦＯＭが０．７００以下である。また、本開示のＨＡＰ粒子の製造方法は、化学沈降法によって、カルシウム源及びリン酸源を、ｐＨが９．０超１３．５以下の水溶液中で反応させる工程を含む。【選択図】 図１
