摘要

Fe2O3-CaO-SiO2 glass ceramics containing nucleation agent P2O5/TiO2 were prepared by sol-gel method. The samples were characterized by X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The activation energy and kinetic parameters for crystallization of the samples were calculated by the Johnson-Mehi-Avrami (JMA) model and Augis-Bennett method according to the results of DSC. The results showed that the crystallization mechanism of Fe2O3-CaO-SiO2 glass, whose non-isothermal kinetic parameter n = 2.3, was consistent with surface crystallization of the JMA model. The kinetics model function of Fe2O3-CaO-SiO2 glass, f(alpha) = 2.3(1-alpha)[-ln(1-alpha)](0.57), was also obtained. The addition of nucleation agent P2O5/TiO2 could reduce the activation energy, which made the crystal growth modes change from onedimensional to three-dimensional.
