-
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.
