PURPOSE:To obtain hydroxyapatite which is not converted to ceramics and has high adsorption capacity, by suspending a water-insoluble calcium phosphate and water-insoluble CaCO3 in water at specific ratios and reacting the components with each other. CONSTITUTION:One or more kinds of water-insoluble calcium phosphates selected from CaHPO4.2H2O, CaHPO4, Ca2P2O7, Ca8H2(PO4)6.5H2O and Ca3(PO4)2 are prepared beforehand and suspended in water. Water-insoluble CaCO3 is added to the suspension at a Ca/P molar ratio of 1.67. The components are made to react with each other by heating the suspension under stirring.
