Summary:To investigate the effects of Fe 2 O 3 addition on the crystallization and structure of glass ceramics, the iron coordination states were characterized using Mössbauer spectroscopy, and the activation energy of crystallization was calculated according to differential scanning calorimetry results. The results showed that the Fe III coordination states changed from tetrahedron to octahedron when the Fe 2 O 3 content is larger than 20%, where the activation energy of crystallization for B1 is the lowest. This work can provide guidance for the preparation of CaO–Fe 2 O 3 –SiO 2 glass ceramics.
