摘要： A method of preparing graphite intercalation compounds in which graphite particles are immersed in an aqueous electrolyte media comprising both an acid and an oxidizing agent. The immersed graphite particles are subjected to an anodic current and then removed from the electrolyte and rinsed with a solvent. The excess solvent and electrolyte is then removed from the graphite particles. The graphite particles may be placed in a plating barrel which is immersed in the electrolyte and rotated while the graphite particles are subjected to the current. The resultant intercalated graphite has an expansion volume of from between about 100 ml/g to 2000 ml/g when heated to 1000°C.

摘要： The present invention comprises an improved method of consolidating particulate materials or combinations of such materials into shaped products of very low porosity. High compac­tion pressures are applied at temperatures in the range of sintering temperature of the materials being consolidated to achieve essentially complete densification at extremely rapid processing rates. Electrothermal heating is utilized to accomplish these results. Difficult materials such as silicon carbide, boron carbide and other very high melting point materials may be densified by these techni­ques.

摘要： A method for improving the thermal characteristics of cement compositions is provided in which fine resilient graphitic carbon particles ("RGC") are substituted for a portion of the fine aggregate (typically send) in the cement formulation. For the purposes of the present disclosure, "fine" is intended to describe particulates having a mesh size of less than about 8 mesh, or a particle size of less than about 2.38 mm, or, more preferably when referring to RGC, a mesh size of less than about 16 mesh and a particle size of less than about 1.19 mm. "Resilient" is intended to describe graphitic carbon particles that exhibit a rebound of at least about 20% after compression to 10,000 psi.

摘要： A coated particulate is provided with a graphite-impregnated resin coating. The oil field particulates may comprise any of gravel -pack sand, granular betonite, ground Gilsonite, calcium carbonate, glass beads, rock wool, shredded paper, metal spheres, ceramic beads, nut hulls, ground rubber, plastic beads, muscovite mica, calcined petroleum coke, and perlite. The resin may comprise as a binder one or more of a natural, synthetic, water-soluble, and organic resins. More specifically, the resins may comprise an organic film-forming resin such as an alkyd, polyurethane and epoxy. Alternatively, the resin may comprise a film-forming water-soluble polymer, such as a starch, carboxymethyl cellulose, hydroxyethyl cellulose, and xanthan gum. In a further alternative, the resin may comprise a resin-dispersed emulsion, such as a latex or acrylic .

摘要： An electro thermal fluidized bed furnace is adapted to be used in a process for continuously heat treating of fine particulate matter, such as carbon black material, by continuously introducing a non-reactive fluidizing gas through the nozzles of the furnace at a pre-determined rate, continuously introducing untreated carbon black material through the feed pipe of the furnace at a predetermined rate so that it forms a fluidized bed, energizing the electrode so as to heat the fluidized bed, and continuously collecting the treated carbon black from the discharge pipe. The carbon black collected from the discharge pipe exhibits properties of having the PAHs and sulfur removed, the carbon black has been graphitized, the moisture pick-up by the carbon black has been eliminated and the carbon black is more oxidation resistant, Furthermore, the resultant furnace carbon backs have a particle size of 7-100nm and an oil absorption number of 50-300 ml/100g., while the thermal blacks have a particle size of 200-500 nm and an oil absorption number of less than 50 ml/100g. Provides thermally modified carbon blacks having improved performance properties in food contact type applications, moisture cured polymer systems, zinc-carbon dry cell battery applications, other electrochemical power sources and other electronic applications, semi-conductive wire and cable applications, and bladder compounds which show both improved thermal conductivity and improved processability.

摘要： An electrically conductive paving system that has enhanced conductivity of the conductive graphite/asphalt layer. This is achieved by incorporating into the paving mixture a blend of two naturally occurring crystalline flake graphites, one being coarse (generally larger than 40 mesh/425 microns) and the other being fine (generally smaller than 100-200 mesh/150-75 microns). The ratio of course flake graphite to fine flake graphite may be from 1.5:1 and 1:1.5, but is preferably approximately 1:1.

摘要： A method for making expanded graphite from lamellar flake graphite comprising first providing lamellar flake graphite particles having at least a minimal purity, then intercalating the lamellar flake graphite particles with an expandable graphite intercalation compound, followed by expanding the graphite intercalation compound to exfoliate the flake graphite particles, and finally air milling the exfoliated flake graphite particles to further delaminate them.
