【Abstract】 In order to investigate the bioactivity of calcium iron silicate ferromagnetic glass-ceramics useful as thermoseeds for hyperthermia treatment to tumor,the sample surfaces were examined by SEM, AES, FT-IR, after being soaked in the simulated body fluid. The results showed that the carbonate-hydroxylapatite layer, capable of combining with body tissue intimately, was formed on the Si-rich layer of sample surface. It is predictive that the calcium iron silicate glass-ceramics have good bioactivity.更多还原
