Hydroxyapatite (HA) powders were prepared by hydrothermal treatment of CaHPO₄·2H₂O with Ca(OH)₂ and characterized by XRD, FTIR, SEM, TEM. The results indicate that pH value and temperature show great influences on the structure and morphology of the products. At pH=9 and 120℃, the HA whis-kers were obtained with an aspect ratio>20, and typical diameter and length of 40 nm and 600 nm, respectively.
