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 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 needlelike.
