Abstract
This report describes certain graphite base composites capable of resisting oxidation by forming a protective coating from their oxidation products. When first exposed to oxidizing conditions, the additives or graphite-additive reactants oxidize and form a coating which protects the composite against further oxidation. Since these materials are homogeneous composites, they can be machined without destroying their oxidation resistant characteristics. The most effective additives investigated were combinations of ZrB2, Si, B, Cb, and Th. All materials were prepared in a one step operation by hot pressing. The report describes the equipment required to fabricate graphite-refractory composites by hot pressing at temperatures up to 3100°C. Oxidation test methods employ indirect induction heating, resistance heating, arc image techniques, and electromagnetic levitation.
