摘要：

The mechanism of the apatite formation induced by silicate ions on a collodion film was examined by TEM-EDX. The TEM-EDX showed that the collodion film is first attached with the Si within 6 hours, then with the Ca within further 6 hours and finally with the P within further 12 hours. The product at the final stage was identified as an apatite by electron diffraction. These results indicate that the silicate ion which is dissolved from the CaO, SiO2-based glass and attached on the surface of the polymer induces the formation of the apatite through the formation of a certain calcium silicate.
