| 摘 要： | Objective: To prepare hydroxyapatite cement (or calcium phosphate cement,CPC) and analyze its capability. Methods: Tetracalcium phospluge (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 compressive strength were measured also. Results: The main element of CPC is hydroxyapatile (HA), its microstructure comprised of petal crys-tals. The diameter of micropore was 4-10μm, density was 1. 922 g/cm^3, 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.
