Abstract
It is an object to provide an aluminum oxycarbide composition capable of suppressing oxidation of AlOC during use to maintain advantageous effects of AlOC for a long time. In an aluminum oxycarbide composition comprising AlOC crystals, the AlOC crystals have an average diameter of 20 μm or more, based on an assumption that a cross-sectional area of each AlOC 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.
