Abstract
The reactions of sintered zirconium and titanium carbides have been studied in simulated rocket combustion gases at surface temperatures of about 2250° C. Under these conditions zirconium carbide is oxidized according to a parabolic law owing to the formation of an adherent oxide film. No oxide film is formed on titanium carbide under the same conditions, and it decreases in weight and dimensions at a relatively rapid rate.
