Sintering behaviour of carbonated hydroxyapatite prepared at different carbonate and phosphate ratios

In the present work, the effect of varying the carbonate to phosphate (CO32−/PO43−) molar ratios from 0.5 to 4 on the sintering behaviour of carbonated hydroxyapatite (CHA) synthesized by a wet chemical method were investigated. The sintering was performed under carbon dioxide atmosphere at 900 °C to maintain the B-type CHA structure. The derived powders as well as the sintered samples were characterized to determine the phase present,...
