| Abstract: | The glass-ceramics in MgO-Al2O3-SiO2 system were prepared by high temperature melting method.DTA and XRD were used to investigate the heat-treated process and mechanical properties of different samples.The effects of crystallization temperature,crystallization time,nucleation temperature and nucleation time on mechanical performance and micro-structure of the glass-ceramics were discussed in detail.The results show that in the MgO-Al2O3-SiO2 system,cordierite-based glass-ceramics with better properties are obtained through a nucleation treatment at 600℃ for 4h,subsequently a crystallization treatment at 1100℃ for 2h,and the flexure strength is up to 182MPa. |
