Abstract

The modification of carbon mass for self-igniting anodes is considered. The mass consists of a binder–filler system. The modifier employed is the phenolic fraction of coal tar. The filler is anthracite treated at 1800°C. The binder is moderate-temperature electrode pitch (grade B). Research shows that cocarbonization of the modifier in the binder–filler system on heating may consist of two processes: 1) before transition of the pitch to a viscofluid state, the additive facilitates mutual approach of its macromolecules and expands the temperature range of nucleation of graphite-like structures; 2) on account of adhesive forces, the phenolic fraction is attached to the filler (thermoanthracite) surface. That, in turn, should intensify the wetting, adsorption, adhesion, and sintering capacity of the electrode pitch (binder).
