Mullite-alumina refractories with combined nitride-containing binders

Formation of a combined nitride-containing binder for mullite-alumina refractories is studied. An optimal combination is found to consist of 80% crystalline silicon, 10% silicon carbide, and 10% aluminum, magnium, or zirconium oxide. Mullite-alumina refractories with selected binders showed high resistance to the effects of slag, alkali, and iron.Translated from Ogneupory, No. 6, pp. 9–13, June, 1994.
