Description
Summary:In this work, hydroxyapatite-20%wt titanium (HAp-20%.wt Ti) nanocomposite was produced by novel solid state method. The effect of one step mechanochemical process on the formation, structural, and morphological features of HAp-based nanocomposite was explored. Characterization of the products was accomplished by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) techniques. Phase analysis indicated that the milling time and thermal annealing process at 650 °C affected phase stability and structural features of products. The crystallinity degree of mechanosynthesized powders increased after thermal treatment at 650 °C. Morphological evaluation exhibited that the average particle size of resultant powder with ellipse-like morphology reached about 25 ± 15 nm after 20 h of milling. The prepared nanopowders which have an acceptable purity are able to improve the biomedical performances of the calcium phosphate-based nanocomposites owing to possess appropriate morphological and structural features.
