摘要: This paper presents details of the fabrication a glass ceramic, and its application as an artificial bone prosthetic material. new bioglass with composition Na2O 8.4%, CaO 40.6%, P2O5 12% SiO2 39%, had 160–190 MPa 800–980 three-point bending strength compressive respectively. The ceramic has (Na, Ca) (P, Si) O3 crystalline phase uniform crystal size about 10μm, which was attributed to high nucleation frequency. rabbit condyle test showed that material formed tight chemical bond biological texture good biocompatibility.
