Summary: The B-type carbonate hydroxyapatite (CHA) containing Mg cations was synthesized by dry mechanomilling of Indonesian limestone-based hydroxyapatite (HA) and magnesium carbonate (MgCO3). This study innovatively selected MgCO3 as a precursor to donate CO32- and Mg2+ to the HA structure, thus forming CHA-containing Mg cations. The crystalline phases and chemical structure of the synthesized CHA were analyzed using X-ray diffraction, X-ray fluorescence, scanning electron microscopy, and particle size analysis. The feasibility of this work lies in the production of B-type CHA containing Mg cations, which hold potential for biomaterial application.
