Summary:

Earlier studies at Brookhaven have shown a greater total-strength loss for the same mass loss in samples of PGX graphite oxidized in O/sub 2//N/sub 2/ or air, versus H/sub 2/O/He or CO/sub 2//He. Similar studies involving H-451 and IG-11 graphites failed to reveal any effect of oxidant type on strength loss. Evidence gathered via photomicroscopy and x-ray mapping (Fe raster scans) support the cause of this phenomenon as being the differences in the microstructural attack by non-catalytic oxidation versus catalytic oxidation. In this paper, further studies involving various reactor-grade graphites and the possible mechanisms leading to strength-loss differences will be discussed.
