... corrosion resistance. Etching of the core structure showed a selective form of cast iron corrosion (spongiosis or graphitic corrosion) which lowered the strength of the cast iron enough that a knife could scrape off a black powder (10.85% C, 1.8% S, 1.45% P). Analysis showed that some of the “sulfate” found...

With the new generations of “black refractories,” which contain 7% or more carbon materials (mainly natural graphite), adding one or two metallic additions to act as “antioxidants” or to protect carbon is mandatory. The technical ceramics, on the other hand, constitute an ill-defined class...
