The Study of Magnesium Substitution Effect on Physicochemical Properties of Hydroxyapatite
In the present study, pure and Mg-substituted hydroxyapatite powders made up of needle-like and plate-like particles, respectively, have been synthesized by wet chemical precipitation of CaO, MgO and H3PO4. The influence of different amounts of MgO addition into synthesis media on properties of as-synthesized and sintered powders has been evaluated. Through the phase and chemical composition analysis it has been determined that the prepared powders contain various amounts of Mg (in the range between 0.21–4.72 wt%). The substitution of Mg promoted the decomposition of hydroxyapatite to β-tricalcium phosphate.
