Abstract

Cordierite (2MgO.2Al2O3.5SiO2) is commonly used phase for high temperature and thermal shock resistant applications in ceramic industry due to its low thermal expansion and excellent thermal shock resistance. In this study microwave and conventional energy sources were used to form cordierite phase. Sintered magnesia, kaolinite and quartz were used as starting materials. The starting materials were mixed according to stoichiometric ratio of 2MgO.2Al2O3.5SiO2 and compacted as coin shaped test samples by uniaxial pressing. Test samples were sintered for different sintering durations and temperatures by using both energy sources. Obtained products were characterized by XRD analysis and density tests. The results were discussed.
