Abstract
The prepared hydroxyapatite has similar properties in comparison with the originally reported in relation to morphology, particle size and stoichiometric compound: A rod-like morphology with particle size of 20–50 × 100–200 nm, particle average size of 175.9 nm with 1-modal, pore radii of 1.22 nm and stoichiometric and anisotropic. The particles characteristics are single and homogeneous in phase, uniform particle size in the nanometer range and chemical composition (Condon in Microporous Mesopourus Mat 38:359-383) [1], (Juang and Hon in Biomaterials 17:2059-2064) [2]. This process does not include sintering only heat treatment, and it is a HA fabrication advantage. And this does not present oxides or some carbonates traces. This method is easier and cheaper than reported originally (Afshar et al in Mat Des 24:197-202) [3] due to synthesis process which does not involve controlled atmosphere in the reactor at room temperature.
