Effects of B<sub>4</sub>C on the Crystallization and Oxidation Resistance of Carbon from Resin

Abstract

Phenolic resin is widely used as a binder for carbon-containing refractories for its relatively high amount of carbon yield. Carbon from it, however, is the so-called non-graphitizing carbon, therefore its crystallization and oxidation resistance are low. In this study, the effects of B4C which is usually added to carbon-containing refractories as an antioxidant on the crystallization and oxidation resistance of carbon from resin have been investigated. The results show that B4C can accelerate the crystallization of carbon from resin and thus improve the oxidation resistance of the carbon.
