Chesters (16) proposed as a possible mechanism that the carbon reduces ferric oxide (or calcium ferrite) to Fe° or even metallic iron which is virtually non-corrosive to magnesia and lime. White (101) also agreed that the carbon would stop iron oxide attacking the brick for a similar reason provided that enough carbon is retained in the brick.
