Abstract

A heterophase method with elements of mechanical activation for producing mesoporous hydroxyapatite (HA) was proposed and tested. Optimal synthesis conditions were determined. Resulting materials were analyzed using X-ray diffraction (XRD) and IR spectroscopy. Their specific surface area (using the BET method), pore volume, and pore size distribution (based on the BJH model) were determined. Optimal synthesis conditions, including milling in an aqueous medium for at least 20 min, were established. A nanosized mesoporous single-phase HA powder with an average particle size of 20 ± 2 nm, a pore size of 12 nm, and a pore volume of up to 0.29 ± 0.01 cm3/g was obtained.
