Phenolic resin has been widely used as a binder for carbon-containing refractories. Carbon from phenolic resin, however, is so called non-graphitizing carbon and its oxidation resistance is poor. In this paper, oxidation resistance and crystallization of carbon from phenolic resin added to carbon-containing refractories were investigated. In MgO-C refractory, owing to the effect of Mg(g) and CO_2(g) formed by the reaction between MgO and C, the crystallization of the carbon from phenolic resin was enhanced and the oxidation resistance was improved, whereas in Al_2O_3-C refractory, owing to the low equilibrium partial pressure of Al(g), no changes were found in the crystallization and the oxidation resistance of the carbon.
