摘　　要：在无压烧结条件下,制备CaSiO3+B2O3+SrCO3+CaF2+ZnO/HA生物复合材料。用XRD分析复合材料的相组成,用SEM观察其微观结构和形貌。结果表明:随着烧结温度的升高,复合材料的弯曲强度提高;硅灰石以玻璃相填充于材料的间隙,改善了复合材料的强度。The CaSiO3＋B2O3＋SrCO3＋CaF2＋ZnO/HA bioceramic composite was prepared by pressureless sintering. The phase composition was analyzed by XRD and the microstructure was observed by SEM. The results show that the bending strength of the composite increases with the rise of sintering temperature. The glass phase of wollastonite was filled in the clearances of the material, which improves the strength of the composite.
