" /> premium coke - CISMeF





Preferred Label : premium coke;

IUPAC definition : An extremely well graphitizing carbon with a high degree of optical anisotropy (isochromatic areas of optical texture above about 100 µm) and which is characterized by a combination of the following properties which differ significantly from those of regular coke: high real density, low reversible thermal expansion and low ash content combined, in most cases, with low sulfur content.;

Scope note : premium coke is mainly produced from tars or residues from petrochemistry by the delayed coking process. also, refined coal tar pitches are used as precursors for premium coke production.;
