Microwave-assisted Synthesis of Highly Crystalline Mesoporous Hydroxyapatite with a Rod-shaped Morphology

Mesoporous hydroxyapatite (MHA) with a rod-shaped morphology has been successfully synthesized for the first time employing cetyltrimethylammonium bromide (CTAB) as a template and CaCl2 and K2HPO4 as the precursors for hydroxyapatite under alkaline medium at the reaction temperature of 120 °C via microwave method. The obtained material exhibits a disordered mesoporous structure with a high crystallinity and highly uniform rod-like morphology with an average size of ca. 25 nm in width and 100 nm in length.
