Abstract
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 CO2(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 Al2O3-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.
