Biomimetic Mg-substituted hydroxyapatite: from synthesis to in vivo behaviour

The incorporation of magnesium ions (in the range 5–10 mol% in respect to Ca) into the hydroxyapatite structure, which is of great interest for the developing of artificial bone, was performed using magnesium chloride, calcium hydroxide and phosphoric acid, as reactants. Among the synthesized powders, the synthetic HA powder containing 5.7% Mg substituting for calcium was selected, due to its better chemico-physical features, and transformed...
