ABSTRACT:
The present invention provides an electrically conductive material (10) comprising a substantially spherical refractory particle (12) having an exterior surface (14) and having a diameter of no more than about 5 millimeters. An electrically conducting coating (22) substantially equally covers the entire exterior surface (14), the coating (22) having at least about 70 atomic percent carbon and being from about 10 Angstroms to about 500 Angstroms thick. A plurality of such particles (12) are useful as filler materials. Also, such particles (12) are useful as flowing electrodes. Objects containing the particles (12) have desirable electrical properties.
