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 CaCl ₂ and K ₂HPO ₄ 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.
