本文将磷酸氢钙(CaHPO4·2H2O,DCPD)添加到硅酸三钙(Ca3SiO5,C3S)骨水泥中,采用X射线衍射(XRD),扫描电镜(SEM),万能力学测试机等手段对不同添加量的骨水泥进行表征,考察添加DCPD对硅酸三钙骨水泥性能的影响.实验表明,C3S材料中添加10%DCPD有着优于单纯C3S骨水泥的水化性能,骨水泥的初凝时间从92 min缩短到80 min;添加20%～30%DCPD能提高材料的短期力学强度,可以实现其短期抗压强度的优化;添加30%～40%DCPD的材料有着优良的生物活性与适中的可降解性能.结果表明,通过添加DCPD优化C3S水泥的性能.对各种不同性能具有DCPD添加量的依赖性.通过进一步优化DCPD添加量,将可能获得优良的生物活性骨缺陷填充材料.

Dicalcium phosphate dihydrate (DCPD) was added into C3S bone cements.The cements were characterized with XRD,SEM,and mechanical test to investigate the effect of DCPD.The experiment showed that Ca3SiO5 bone cements added with 10% DCPD had better hydraulic properties than pure C3S bone cement and its initial setting time was reduced from 92 to 80 minutes.The short-term mechanical strengths of the materials were promoted by adding with 20%～30%DCPD,and the short-term mechanical strength could be optimized.The materials have better bioactivities and moderate degradability by adding with 30%～40% DCPD.The results demonstrated that the properties of C3S cement could be improved by the addition of DCPD,and the different properties of C3S cement could be regulated by the amount of DCPD addition.It is expected to obtain excellent bioactive bone defect filling materials by optimizing the ratio of DCPD in the cement.
