Salah A. Abo-El-Enein et. al. 9 performed a research work in which bauxite-based and kaolin-based refractory castables were carefully prepared with a binder mixture of 80 alumina and MA-spinel either preformed or in situ. The XRD patterns showed that a corundum phase and a mullite phase is formed in all of the bauxite-based castable
