Preparation and Characterization of Hydroxyapatite Whiskers

Abstract:

The HAP whiskers were prepared by hydrothermal homogeneous precipitation method at the constant temperature. Diammonium hydrogen phosphate, calcium nitrate tetrahydrate, urea and nitric acid were used as the main raw materials. Sorbitol was selected as the template agent and the hydroxyapatite whiskers seeds were served as the inducers. SEM, TEM, XRD and EDS were applied in characterization. The results show that the reaction products are the HAP whiskers with high crystallinity, smooth appearance and no agglomeration; the obtained HAP whiskers are monocrystal and the length-diameter ratio distribution of the HAP whiskers is concentrated at about 30.
