Study on Physicochemical Properties of the Carbonated Hydroxyapatite Bone Cement
Carbonated hydroxyapatite (CHA) bone cement is capable of self-setting and has the component similar to the mineral phase of natural bone. But it is compact in structure and short of cavity, which limits new bone growing into CHA bone cement. In this paper, the foaming method was adopted to prepare the porous CHA. The setting time, compressive strength, porosity and pore size of the CHA were examined. The phase composition of the CHA was tested with XRD and FT-IR. The microstructure of the CHA was observed with SEM. The results show that setting time of 7~19 minutes, compressive strength of 26~32MPa, pore size of 100~200µm, porosity of 50~60%.
