N2 - The mixture of dicalcium phosphate dihydrate (DCPD) and calcium acetate monohydrate were hydrothermally treated in a condition of water-ethanol mixed solvent at 120 °C for various periods. The rate of hydroxyapatite (HAp) formation was decreased with increasing the volume ratio of ethanol, to result in formation of dicalcium phosphate anhydrous and β-tricalcium phosphate. Needle-like HAp particles were observed in the sample treated with the mere water. The sample treated with the ethanol-water mixed solvent had nano-sized HAp particles with a form of the plate-like crystals. The size of HAp crystal was decreased with increasing the fraction of ethanol. These results show that HAp formation and crystal growth were prevented by the ethanol addition.
