✦ Synopsis

The gasification rate of Great Lakes H-440 graphite was studied using either CO, or H,O as the reactant, while at the same time applying varying compressive stresses to the samples of up to 10% of the compressive strength. The concentrations of reaction products were continuously monitored using high sensitivity IR gas analyzers. In no case was any change in reactivity detected when a change in stress was made. This result contradicts reports by other workers using tensile stresses. An analysis of possible explanations for these early reports shows that none are able to explain the magnitudes of the effects described in these early reports.
