May 18 2012 · The composition Al2O3 ZrO2 (99.1 wt ) when fused inthe arc furnace and quenched in H2O yielded a new phase e-Al2O3. The phase was indexedon a hexagonal unit cell but with several low-angle peaks unaccounted for. The new phasewas verified by high-temperature X-ray diffractometry using an IR strip furnace and opticalpyrometry.

Nevertheless for higher cement alumina content castables the formation of cracks is observed in refractory castables into which slag deposit can penetrate. The slag reacts with alumina to form a new phase such as hibonite (CA6) and calcium dialuminate (CA2). The expansive reactions involving CA2 and CA6 lead to the apparition of macro-cracks.
