Aluminum oxycarbide composition, production method therefor, and refractory material
It is an object to provide an aluminum oxycarbide composition capable of suppressing oxidation of Al4O4C during use to maintain advantageous effects of Al4O4C for a long time. In an aluminum oxycarbide composition comprising Al4O4C crystals, the Al4O4C crystals have an average diameter of 20 μm or m...

| description | It is an object to provide an aluminum oxycarbide composition capable of suppressing oxidation of Al4O4C during use to maintain advantageous effects of Al4O4C for a long time. In an aluminum oxycarbide composition comprising Al4O4C crystals, the Al4O4C crystals have an average diameter of 20 μm or more, based on an assumption that a cross-sectional area of each Al4O4C 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. |
