Definition
The main constituent of a carbon artifact, introduced as solid component (predominantly in the form of particulate carbon) into the 'carbon mix' from which polygranular carbon and graphite materials are obtained by heat treatment.

Note
Filler coke is not necessarily the only, but it is commonly the most important filler material used in a 'carbon mix' which consists of filler and binder.
