摘要

The effect of Fe_2O_3-TiO_2 mixture additives on the crystallization behaviour of a parent glass with composition located in the primary field of cordierite within the MgO-Al_2O_3-SiO_2 system has been examined. The crystallization behaviour of the glass was determined by differential thermal analysis (DTA) and X-ray diffraction (XRD). The microstructure was characterized by scanning electron microscopy (SEM). The results show that additives of Fe_2O_3-TiO_2 can lower the temperature of the crystallization peak (T_p) and promote crystallization of the parent glass. By controlled thermal treatment, the main crystal phase obtained was Fe~(2+) substituted α-cordierite. The approach outlined in this paper to obtain heterogeneous ion substituted cordierite glass-ceramics is useful to develop infrared radiation material with good properties.
