THE EFFECT OF CRYOLITE NA3ALF6 AND SODIUM FLUORIDE NAF ON THE CORROSION AND WETTING BY MOLTEN AL-SI ALLOY OF ANDALUSITE BASED REFRACTORIES
Research Paper
Research Paper
In order to improve the corrosion resistance of aluminosilicate refractories by molten aluminum, alkaline
fluoride NaF and cryolite Na3AlF6 powders were studied. Both physical and chemical properties are known to
influence wetting and corrosion behavior. This paper devoted to determine the influence of alkaline fluoride and
cryolite added to andalusite based castable on the reaction with aluminum alloys. These additives led to the in-situ
formation of celsian phases within the refractory matrix that led to improved corrosion resistance at 1300°C. Phase
analysis revealed that celsian formation suppressed the formation of mullite within refractories, thereby reducing
