| Abstract: | Objective: To prepare hydroxyapatite cement (or calcium phosphate cement, CPC) and analyze its capability. Methods: Tetracalcium phosphate (TTCP) was prepared by the method of high heat. TTCP reacted with in simulated body situation and produced CPC, Its capability was analyzed by scanning electron microscopy (SEM) , X-ray diffraction(XRD). Its density, absorbing water coefficient, macroporosity and campressive strength were measured also. Results: The main element of CPC is hydroxyapatite (HA) , its microstructure comprised of needlelike or petal crystals. The diameter of micropore was 4-10 nm, density was 1.922 g/cm3, macroporosity was 29. 777% , absorbing coefficient was 15. 503%, compressive strength was 42. 70 Mpa. Conclusion: This CPC has three-dimensional spatial structure, its strength meets the need of cancellous bone grafting. |
