Dissolution in Ceramic Systems: 11, Dissolution of Aluminu, Mullite, Anorthite, and Silica in a Calcium‐Aluminum‐Silicate Slag

摘要: Experimental measurements have been made on the rate of dissolution sapphire, dense poly-crystalline alumina, mullite, fused silica, and anorthite in a 20A12O3-4OCaO-40SiO2 slag at 1350° to 1500° C under conditions free forced convection. Dissolution rates their temperature dependence were found be controlled by transport within liquid boundary layer. At low temperatures alumina is far most corrosion resistant; higher differences between refractories tested are less pronounced.
