Preferred Label : needle coke;
IUPAC definition : The commonly used term for a special type of coke with extremely high graphitizability
resulting from a strong preferred parallel orientation of its turbostratic layer structure
and a particular physical shape of the grains.;
Scope note : needle coke is derived mainly from clean (i.e. lacking hetero atoms and solids) and
highly aromatic (i.e. several condensed rings per cluster) feedstocks with a very
low concentration of insolubles. upon solidification a material with a distinctive
streaked or flow-like macroscopic appearance is produced. upon grinding the coke breaks
up first into macroscopic needles and then, after further grinding, into microplatelets.
sometimes the word acicular is used as a synonym for needle-like.;
