Synthesis of carbonate hydroxyapatite contained magnesium cations by dry mechano-milling

摘要

? 2023 Elsevier B.V.The B-type carbonate hydroxyapatite (CHA) containing Mg cations was synthesized through the dry mechano-milling between Indonesian limestone-based hydroxyapatite (HA) and magnesium carbonate (MgCO3). The novelty in this research is the selection of MgCO3 as a precursor that will donate CO32? and Mg2+ to the HA structure to form CHA-containing Mg cations. The crystalline phases and chemical structure of synthesized CHA were studied by X-ray diffraction, X-ray fluorescence, scanning electron microscope, and a particle size analyzer. The feasibility of this work is to be able to produce B-type CHA containing Mg cations that have the potential to be developed for biomaterial application.
