Description:
The effect of excess MgO mole ratio on the sintering behavior of cordierite ceramic was studied using XRD and SEM. The green bodies were sintered at 1100–1300°C by solid-state method. The excess MgO did not obviously reduce the crystallization temperature but increased the production of liquid and densification. This effect has to be activated by a specific temperature. The starting material had little influence on the crystallization phase at 1200°C or higher. As basic magnesium carbonate can also be used as a pore-forming agent, the shrinkage and porosity approached maximum value at 3.4 mole ratio of MgO.
