Abstract

The homogeneous hydroxyapatite rod-like nanocrystal was prepared through an economical and simple route under gentle conditions by the aqueous chemical method. The high-resolution transmission electron microscope (HRTEM) displayed that the products were well-dispersed nanorods. The diameter of the nanorods was 4 ± 0.1 nm and the length was 20 ± 0.8 nm. The corresponding selected area electron diffraction (SAED) analysis demonstrated that the products were crystalline. Additionally, both X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR) spectra indicated the characteristic peaks of hydroxyapatite. Moreover, the energy dispersive system (EDS) analysis demonstrated the Ca/P ratio of the product was 1.67, which was in consistent with commercial hydroxyapatite.
