Abstract Share this page

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 hydroxyapatite (HA) was prepared by reacting calcium hydroxide and a phosphoric acid solution. The resulting powder was heat treated at 680° C. Two time of aging were applied at 24 and 48 h. 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[1] due to synthesis process which does not involve controlled atmosphere in the reactor at room temperature. The particles characteristics are single and homogeneous in phase, uniform particle size in the nanometer range and chemical composition[2], [8]. The prepared hydroxyapatite has similar properties in comparison with the originally reported in relation to morphology, particle size and stoichiometric compound.
