Development of MgO-C Refractory Having High Oxidation Resistance by Metal Coating Process.

Graphite has been modified with a coating reagent, which can form coating layer of a metal on the surface of graphite, to effectively prevent the oxidation of graphite used as a carbon source, compared to common antioxidants. The oxidation of graphite is resisted by the high oxidation reactivity of metal and the oxygen barrier effect of coating layer. Therefore, the metal layer should be homogeneously and continuously coated on the surface of graphite and the coating efficiency of metal should be increased.
