The corrosion characteristics of a variety of fused-cast refractories in contact with various coal-ash slags were investigated. A fused-cast chrome-spinel refractory exhibited excellent corrosion resistance to both acidic and basic coal-ash slags at 1500/sup 0/C, even in the absence of water cooling. The slag-refractory interaction was limited to the formation of a stable band of recrystallized hercynitic spinel. Alumina-chromia refractories were superior to alumina and magnesia-chrome refractories when exposed to acidic slags.
