Zusammenfassung:	PURPOSE:To manufacture quantitatively the titled apatite of high grade with high reproducibility at a low cost by reacting phosphoric acid or Ca phosphate with CaCO3 in a reaction medium contg. an org. solvent. CONSTITUTION:Phosphoric acid and/or Ca phosphate and CaCO3 are charged into a reaction vessel in a desired ratio of Ca/P, and a proper amount of water is added to prepare a slurry. An org. solvent is then added to the slurry, and reflux is carried out under heating. Deposited hydroxyapatite contg. carbonate is separated.
