摘要: The oxidation behaviors of different grades nuclear graphite - PAEB, PCEB, PPEA, and IG-11 were studied thermogravimetrically at 400, 800, 1200 deg. C as a part work to select one grade for use in gas turbine-modular helium reactor (GT-MHR). results showed that all resist 400 C. difference between was greater 800 than At C, the same graphite, when centerline specimen is parallel axis extrusion (with grain), rate with perpendicular (against grain). experimental revealed PPEA had best resistance, worst due high impurities. Moreover, experiment exhibited there some oxidizable materials unclear graphite.
