%X CaO-MgO-P2O5-SiO2 glass-ceramic is a new medicinal biologic material. It not only has good biocompatibility but also improves mechanical properties. The kinetic parameters of this glass-ceramic were calculated by differential thermal analysis (DTA) and the JMA equation. The results indicate that the content of TiO2 effects on the crystallization activation energy (E) and the crystal growth index (n). E increases with the increasing of TiO2 content. And E reaches a max value when TiO2 content is about 8.7%. When TiO2 content increases further (>8.7%), E decreases inversely. The rule of n vs TiO2 content is consistent with that of E vs TiO2 content.
