ALUMINUM OXYCARBIDE COMPOSITION, PROCESS FOR PRODUCING SAME AND REFRACTORY
[OBJECT] It is an object to provide an aluminum oxycarbide composition capable of suppressing oxidation of Al 4 O 4 C during use to maintain advantageous effects of Al 4 O 4 C for a long time. [SOLUTION] In an aluminum oxycarbide composition comprising Al 4 O 4 C crystals, the Al 4 O 4 C crystals have an average diameter of 20 µm or more, based on an assumption that a cross-sectional area of each Al 4 O 4 C crystal during observation of the aluminum oxycarbide composition in an arbitrary cross-section thereof is converted into a diameter of a circle having the same area as the cross-sectional area. This aluminum oxycarbide composition can be produced by subjecting a carbon-based raw material and an alumina-based raw material to melting in an arc furnace and then cooling within the arc furnace.
