The present invention provides a method for producing an aluminum oxycarbide composition and a high yield of Al 4 O 4 C, a low Al 4 C 3 content, and a high productivity. That is, in the present invention, the carbonaceous raw material having an average particle diameter of 0.5 mm or less and the alumina raw material having an average particle diameter of 350 μm or less, and the molar ratio (C / Al 2 O 3 ) of the carbonaceous raw material and the alumina raw material are 0.8 to The blend in the range of 2.0 is mixed uniformly so that the variation of the C component is within ± 10%, and the blend is melted in an arc furnace at 1850 ° C or higher. |
