CaSiO3陶瓷作为潜在的生物材料受到广泛研究,它生物活性好,但化学稳定性、生物相容性、烧结以及力学性能不理想.本研究利用固相反应法分别将CaSiO3与TiO2以摩尔比2∶1、3∶1以及5∶1进行混合,在1100℃下煅烧制备了物相为β-CaSiO3与CaTiSiO5的CaSiO3/TiO2复合陶瓷.复合陶瓷的化学稳定性、常压下煅烧的致密度、力学性能比CaSiO3陶瓷都得到了较大提升.随着CaSiO3含量上升,复合陶瓷力学性能及化学稳定性上升,但在模拟体液中诱导磷灰石形成的能力明显下降.研究结果表明,CaSiO3/TiO2复合陶瓷是一种有应用潜力的骨修复材料,且材料性能可通过改变组分实现调控以适应骨修复需要.
