Chemical corrosion mechanisms of magnesia-chromite and chrome-free refractory bricks by copper metal and anode slag. J. Eur. Ceram. Soc. 27 (2007) pp. Corrosion of refractories by slag is a complex phenomenon which depending on the particular system involves many processes such as chemical wear (corrosion) and physical or mechanical wear (erosion) which may act synergistically. No single model can explain all cases of corrosion nor can it explain all corrosion mechanisms of a particular refractory in different environments but the
