Aluminum oxycarbide composition and production method therefor |
摘要 |
Provided is an aluminum oxycarbide composition production method capable of increasing a yield of Al4O4C while reducing a content rate of Al4C3 and 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 mum or less, wherein a mole ratio of the carbon-raw material to the alumina-raw material (C/Al2O3) 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.
