摘要: Abstract Reactive surface area and its evolution play an important role in the oxidation behavior of porous carbon materials. Here, reactive within nuclear graphite grades NBG-18, IG-110, PCEA were examined using chronic experiments interrupted with short thermal gravimetric analyses. To help interpret observed changes area, contribution macropore total was estimated X-ray computed tomography repeated morphological dilations digitally isolated pore structure. For these graphites, by more than order magnitude between 0 70% conversion. Surface roughening, opening evolution, as well late exposure filler material likely contribute to graphites.
