Carbonated hydroxyapatites were synthesized at pH 7.0 and 9.0 with a carbonate content up to 9.2%, in the presence of Zn2+ ions. The uptake of Zn was found to be proportional to the amount of Zn added at precipitation. Chemical, lattice constant, microprobe and thermal analyses indicate incorporation of Zn into the apatite lattice.
