Abstract
Provided is an aluminum oxycarbide composition production method capable of increasing a yield of AlOC while reducing a content rate of AlCand achieving high productivity, and an aluminum oxycarbide composition. The method comprises: preparing a blend substantially consisting of a carbon-raw material having a mean particle diameter of 0.5 mm or less and an alumina-raw material having a mean particle diameter of 350 μm or less, wherein a mole ratio of the carbon-raw material to the alumina-raw material (C/AlO) is in a range of 0.8 to 2.0; homogeneously mixing the blend to allow a variation in C component to fall within ±10%; and melting the obtained mixture in an arc furnace at 1850° C. or more.
