Abstract

MgO and Al2O3 of different reactivity were used to develop magnesium aluminate spinel. This composition was utilized as in-situ spinel former in Al2O3-MgAl2O4-C refractory. Properties like permanent linear change on reheating (PLCR) at increasing heating cycles and microstructure of this refractory was evaluated. It was observed that rate of spinel formation and associated volume expansion is very much related to the reactivity of raw materials. Magnesia and alumina of moderate reactivity develops the optimum PLCR value, which will be suitable for the refractory application in ladles.
