Calcined cokes, anthracites and graphitic materials are used in several high temperature metallurgical processes as base materials for electrodes because some of their physical properties, such as their electrical conductivity, are adequate. Petroleum and metallurgical cokes contain impurities, like S, Fe, V, Na, etc. that can affect undesired chemical reactions. Recently the authors developed thermodynamic models both for organically bounded elemental impurities in carbon (S, H). This thermodynamic model for graphitizable carbon materials is extended to include impurities, physical properties and their behavior around the graphitization temperature. As impurity contents in cokes tend to increase, thermodynamic analysis of the high temperature behavior of impurities can help explaining the reactions in which they are involved.
