摘要
磷酸钙骨水泥是一种新型的骨修复材料,具有良好的生物相容性。针对其机械性能不是很高的弱点,本文研究了钙磷摩尔比、固化液组成、模拟体液浸泡等制备条件对骨水泥力学性能的影响。结果表明,钙磷比为1.67,固化液为模拟体液,浸泡3天可以得到强度相对较高的水化产物。
Calcium phosphate cement(CPC) is a kind of restorative materials with good biological compatibility but poor mechanical proerty. The effects of preparing conditions, such as molar ratio of Ca to P, setting liquid and immersion in simulated body fluid(SBF), on strength performance of CPC were investigated systematically. The results show that the hydration products with higher compressive strength could be gained when molar ratio of Ca to P was 1.67, cement liquid was SBF and 3 days immersion.
