DISPERSION OF COAL TAR PITCH FOR COATING GRAPHITIC MATERIALS AND USE IN ELECTRODE PRODUCTION

DISPERSION OF COAL TAR PITCH FOR COATING GRAPHITIC MATERIALS AND USE IN ELECTRODE PRODUCTION

A dispersion, methods of making the same, applications of the dispersion to graphitic material and the resulting coated particles are disclosed. The dispersion includes ≤55% wt. coal tar pitch (softening point 100° C.-195° C.), ≤60% wt. dispersant, and the balance a non-aromatic solvent such as wate...

Zusammenfassung:A dispersion, methods of making the same, applications of the dispersion to graphitic material and the resulting coated particles are disclosed. The dispersion includes ≤55% wt. coal tar pitch (softening point 100° C.-195° C.), ≤60% wt. dispersant, and the balance a non-aromatic solvent such as water or alcohol. Pitch particles in the dispersion are preferably
