In this paper carbon dissolution studies were carried out on four carbon materials, viz. graphite, commercial charcoal and two metallurgical cokes, coke A and coke B. The rate of carbon dissolution into molten Fe-85%Mn at initial stage at 1550°C, were determined. Characterization of the substrates was accomplished using proximate analysis, surface topography and XRD. The results showed that coke A and coke B had the highest overall dissolution rate and the dissolution rate constant was determined to be 6.73×10-2 cm/s and 5.94×10-2 cm/s respectively The dissolution rate constant for graphite was 3.52×10-2 cm/s and 1.47×10-2 cm/s for charcoal. Within poorly ordered carbon materials (charcoal and cokes) crystallite size and surface roughness seemed to be dominant factors affecting the dissolution rates. The dissolution mechanism was found to be both mass transfer and interfacial reaction.
