Production and Characterization of Zinc Substituted Hydroxyapatite
Zinc substituted hydroxyapatite of varying wt% was produced using a precipitation method based on reacting calcium and zinc nitrate with ammonium phosphate. Characterisation results from X-ray diffraction (XRD) and X-ray fluorescence spectroscopy (XRF) showed that zinc was successfully substituted up to 0.8wt% using this method. Rietveld analysis showed that the alattice parameter was reduced and c-lattice parameter was increased with increasing zinc content. Initial mechanical test results showed samples with a zinc content of 0.4% had the greatest compressive strength.
