Preparation and Characterization of Hydroxyapatite Whiskers

Abstract:

Hydroxyapatite whiskers were prepared with diammonium hydrogen phosphate, calcium nitrate, nitric acid, sorbitol, HAP seed and carbamide by hydrothermal homogeneous precipitation. The HAP seeds served as whiskers nuclei and sorbitol served as template. The prepared hydroxyapatite whiskers were characterized by XRD,SEM and FTIR. It was indicated that hydroxyapatite whiskers with high crystallinity grew alone Z axis with carbonated trend, and the appearance of HAP was smooth, less magazine and no reunion, the length-diameter ratio of the whiskers was in range of 125-8 with the average is 32.78.
