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.;
Origin ID : P04814;
