Abstract

Alumina-magnesia-chromic oxide refractory compositions yield remarkably stronger and less expansion- susceptible mouldings upon firing, when modified so they contain at least 1% by weight of zircon flour, and firing temperatures can be lowered or firing times reduced. An exemplary composition is a blend of particulate alumina, 35 to 97%, with 1 to 10% zircon flour, particulate magnesia and particulate chromic oxide, the latter two components being 1 to 10% the percentages are by weight of the blend. Molten metal erosion resistance of the fired zircon-containing refractory is such that the compositions lend themselves to the production of orificed, metal teeming components.
