Abstract
The effects of oxide impurities on the strength of alumina based refractories after thermal cycling have been investigated using the water quench test. Aluminous, high alumina and alumina-chrome samples were tested. The experimental damage was characterised by visual inspection and determining the residual physical and mechanical properties. The results show that the thermal stability of alumina based refractories strongly depends on the oxide impurities present. High oxide impurity content reduced the thermal shock resistance of alumina refractories investigated. Alumina-chrome had the least strength after thermal cycling followed by high alumina and aluminous bricks, respectively.
