This paper studied the Na sub(2)O-B sub(2)O sub(3)-SiO sub(2)-CaO-P sub(2)O sub(5)-F glass-ceramics and obtained the complex biological glass-ceramics with low sintering temperature, high mechanical properties and good biological activity. In this paper, the better basic point was selected in phase region of Na sub(2)O-B sub(2)O sub(3)-SiO sub(2) glass system. It was studied that the effect of different percent of CaO, P sub(2)O sub(5) and F addition on the mechanical properties and biological activity of the glass-ceramics. The glass powder was prepared by melting and quenching in water, and then by molding and sintering, composite glass-ceramics materials was obtained. With the help of DSC, XRD and SEN analysis methods and testing means, the phases and heat treatment systems of the material were determined, and the microstructure of materials in the different heat treatment conditions was observed. The biological activity was tested in SBF simulated body fluid . Research shows that: the introduction of F can effectively reduce the melting temperature of the material and is helpful to crystallization. The introduction amount of CaO, P sub(2)O sub(5) and F can affect the biological activity of glass-ceramics. In the range of introducing CaO, P sub(2)O sub(5) and F In this paper, the mechanical properties and biological activity of glass-ceramics Increase with the amount of the introduction ofCaO, P sub(2)O sub(5) and F.
