The solvent has a boiling point of greater than 75°C and is added to the resole type phenolic resin to impart a viscosity range of between 1 to 1000 poise. The tar/pitch component is combined in the solvent-resin mixture, and is incorporated within the ratios of 30 : 70 to 70 : 30 with relation to the phenolic resin. The binder results in a high carbon binder.
