ABSTRACT:
This invention provides a novel asphalt composition suitable for use as a binder for carbon electrodes which consists essentially of a homogeneous blend of three organic materials comprising (1) a highly aromatic hydrocarbon solvent having a specific combination of physical properties and chemical constituency, (2) a benzene-soluble fraction of solvent-refined coal and/or solvent-refined wood, and (3) a benzene-insoluble fraction of solvent-refined coal and/or solvent-refined wood. The novel asphaltic compositions is characterized by low sulfur content and high binding strength, which are desirable properties for application as a carbon electrode binder.
