摘要：
Spherical hydroxyapatite (HA) crystals were prepared successfully with beta-cyclodextrin (beta-CD) as template by biomimetic method. Their properties were characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscope (FTIR), thermogravimetric analyzer (TG), and scanning electron microscope (SEM). The results show that the concentration of beta-CD) have a significant effect on the morphology of HA crystals. Spherical HA crystals with the diameter of 1.0-3.0 mu m can be obtained in the presence of 1.5% beta-CD. The obtained crystals are the composites of HA/beta-CD. This is a result of the interaction between HA and beta-CD. (C) 2008 Elsevier B.V.. All rights reserved.
