Experimental measurements have been made on the rate of dissolution of sapphire, dense poly‐crystalline alumina, mullite, fused silica, and anorthite in a 20A1 2 O 3 ‐4OCaO‐40SiO 2 slag at 1350° to 1500° C under conditions of free and forced convection. Dissolution rates and their temperature dependence were found to be controlled by transport within the liquid boundary layer. At low temperatures alumina is by far the most corrosion resistant; at higher temperatures differences between the refractories tested are less pronounced.
