Synthesis of magnesium- and manganese-doped hydroxyapatite structures assisted by the simultaneous incorporation of strontium

Sr2 + ions were easily incorporated into the HA lattice, whereas Mg2 + and Mn2 + ions were hardly retained in the HA structure after heating to 1000 °C when they were individually incorporated in the samples. Nevertheless, co-substitution with Sr2 + ions allowed for better fixation of the Mg2 + and Mn2 + ions into the HA lattice.69
