The Preparation and Evaluation of α-CSH/β-TCP Combined Artificial Bone
2011
In this paper, the combined artificial bone made from α- calcium sulphate hemihydrate(α-CSH) and β- tricalcium phosphate (β-TCP) was investigated and at the same time the study explored: the method of preparing the combined artificial bone. Scanning electron microscopy (SEM), Powder X-ray diffraction (XRD), Thermogravimetric (TG), Differential scanning calorimetry (DSC), and Mercury porosimeter were employed to characterize the samples. Results indicate that the combined artificial bone can be prepared by α-CSH and β-TCP using dehydrated alcohol as a solvent; β-TCP was made from cancellous bone in the femur of cattle under special conditions, which contained the spatial structure of normal cancellous bone; α-CSH was made from CSD under special temperature and pressure, which is more pure and regulation in crystal form.
