| Abstract: |
| Cordierite-based MgO-Al2O3-SiO2(MAS) glass-ceramics were prepared by traditional melting-casting method with stone powder as main materials. Effects of Fe2O3 on crystallization and microstructure of cordierite-based MAS glass-ceramic were investigated by differential scanning calorimetry (DSC), X-ray diffraction analysis (XRD), and scanning electron microscopy (SEM). It is found that the primary phase of sample is cordierite and the secondary phase is enstatite. Glass transition temperature and crystallization temperature of sample drop gradually with increasing addition of Fe2O3. Fe2O3 enriches in glass phase and is beneficial to crystallization of cordierite. Length-diameter ratio of cordierite crystal drops with increase of addition of Fe2O3. |
