Abstract
In this study, attempts were undertaken to explore the possibilities to prepare cordierite–mullite composites with potentiality to be used as refractory materials from natural raw materials. Solid state reaction sintering different sample powders at different temperatures from 1,250 to 1,400°C has been applied to prepare cordierite–mullite ceramics. XRD has proved the presence of cordierite and mullite in different ratios as major phases. Thermal shock test method based on heating–quenching procedure, supplemented by scanning electron microscopy and mercury intrusion porosimeter, has been used to demonstrate the thermal stability of different samples.
