中文摘要：

采用冷等静压技术，在150MPa的压力下对磷酸钙骨水泥粉体进行等静压处理，然后使其在一定的条件下进行水化。采用扫描电镜（Scanning electron microscope，SEM）、红外光谱（Fourier transform infrared spectrome-try，FTIR）、X射线衍射（X-raydiffraction，XRD）和压汞仪等测试手段对其水化产物的结构和性能进行研究。结果表明，经过等静压处理，磷酸钙骨水泥粉体水qLg,境被改变，部分水化产物的晶体形貌由细小的短棒状变为六棱柱状，但主要物相仍为羟基磷灰石；水化固化体的孔隙率由未经等静压处理时的（46．32±2．70）％降到（24．75±1．15）％，抗压强度由（12．62±2．70）MPa提高到（43．05±2．08）MPa。

英文摘要：

Calcium phosphate cement（CPC） hydrated in a special environment after compressively treated by cold isostatic pressing technology at 150MPa. The hydrated products are characterized by scanning electron microscope （SEM）, Fourier transform infrared spectrometry （FTIR）, X-ray diffraction （XRD） and compressive strength of the hydrated bodies is tested with a universal materials testing machine. The results indicate that, under the isostatic pressing, the hydration environment of the CPC power is changed. The crystal morphology of a part of the hydrated products changes from short-rod-like to hexagonal-prism-like, but the main phase present in the hydrated bodies is still poorly crystalline hydroxyapatite（HA）. The porosity of the hydrated bodies reduces form （46. 32±2. 70）% without i- sostatic pressing to （24. 75±1.15）% after isostatic pressing at 150MPa and the compressive strength of the hydrated bodies increased about 3. 6 times from （12. 62±2.70）MPa to （43. 05±2. 08）MPa.
