Summary

Simulated body fluid (SBF) and three kinds of bioactive glasses were prepared for bioactivity evaluation tests. These glasses have different bioactiviity due to the different Na2O–CaO–SiO2 chemical composition. The glass surface after being soaked in the SBF was studied by thin film X–ray diffraction spectrometry (TF–XRD) and scanning electron microscope-energy dispersion x-roy spectrometry (SEM–EDS). Soaking time to identify hydroxyapatite precipitated on the surface of the bioglasses in the SBF was measured by TF–XRD. Based on the analysis of bioactivity of the glass and the soaking time, a new index to evaluate ihe bioactivity of materials was proposed.
