- - Method for improvement of oxidation resistance in graphite for MgO-C refractory through surface modification and MgO-C refractory by the same

摘要

The present invention relates to a method for enhancing the antioxidative properties of graphite, and particularly relates to a method for improving surface oxidation of a graphite particle surface by an acid treatment before coating the graphite surface with an aluminum precursor to improve the efficiency of coating a metal precursor on the graphite surface The present invention relates to a method for enhancing the antioxidative activity of graphite contained in magnesia-carbon refractories through surface modification capable of enhancing the antioxidative properties of graphite, and to a magnesia-carbon refractory produced thereby.
