| Abstract: | High_quality cordierite was synthesized by using a special ore material--rectorite and talcum powder. The synthesizing process of the cordierite was systematically investigated and the sample properties of water absorption, porosity, density, thermal expansion coefficient, etc . were tested and the microstructure characteristics were observed by XRD, SEM. The results show that the cordierite can be synthesized at a lower temperature and within a wider temperature range when using the rectorite. |
