Study of Spinel-Containing High Alumina Castable with Different Cements

Abstract

High alumina castable with presynthesized and in situ spinel formation is studied using two different lime-containing high alumina cements. Vibratable castable compositions were studied by conventional processing, using a distribution coefficient of 0.29 and heat treatments at 110, 900, and 1500°C. Slightly lower density and strength values were found for in situ spinel-forming compositions and spinel formation was observed to start around 900°C and near completion at 1500°C in the matrix of the castables.
