Some 60 different refractories were exposed to both acidic and basic molten slags at temperatures between 1500 and 1600 C. A dense, fused-cast chrome-spinel refractory showed superior resistance to corrosion by a wide variety of coal slags. Refractories containing >30% chromia reacted with all types of slags to form complex spinel-reaction products. Alumina refractories were intermediate in performance in acidic slags and poor in basic slags. Magnesia-chrome refractories containing free MgO performed poorly in acidic slags but somewhat better in basic slags. Preferential dissolution of MgO was observed in all cases.
