20080308415 | Cathodes for Aluminum Electrolysis Cell with Expanded Graphite Lining - Cathodes for aluminum electrolysis cells are formed of cathode blocks and current collector bars attached to those blocks. The cathode slots receiving the collector bar are lined with expanded graphite lining thus providing longer useful lifetime of such cathodes and increased cell productivity. The expanded graphite provides a good electrical and thermal conductivity especially with its plane layer. | 12-18-2008 |
20100096258 | REDUCED VOLTAGE DROP ANODE ASSEMBLY FOR ALUMINUM ELECTROLYSIS CELL, METHOD OF MANUFACTURING ANODE ASSEMBLIES AND ALUMINUM ELECTROLYSIS CELL - An anode assembly for aluminum electrolysis cells includes carbon anodes with stubholes and an anode hanger having stubs, in which the anodes are fixed to the anode hanger by cast iron and the stubholes are fully or partially lined with an expanded graphite lining. The anode assembly provides a reduced voltage drop across an interface between the cast iron and the carbon anode and thus increases cell productivity significantly. Mechanical stresses in the stubhole area are reduced. A collar formed from the lining prevents spilling of cast iron over the anode surface and a protective shot plug or a protective collar optionally prevent direct contact of a hot electrolyte bath with the stub and the cast iron. A method of manufacturing anode assemblies and an aluminum electrolysis cell, are also provided. | 04-22-2010 |
20100116457 | METHOD FOR PRODUCING A LATENT HEAT STORAGE MATERIAL - A method for producing a latent heat storage material from a graphitic starting material selected from the group consisting of natural graphite, expanded graphite, and/or graphite fibers, and from a phase-changing material selected from the group consisting of sugar alcohols, water, organic acids and the mixtures thereof, aqueous salt solutions, salt hydrates, mixtures of salt hydrates, salt hydrates with paraffins, inorganic and organic salts and eutectic salt mixtures, clathrates and alkali metal hydroxides, as well as mixtures of these materials. The graphitic starting material is treated with a plasma before being impregnated with the phase-changing material. A latent heat storage material is produced according to the method. | 05-13-2010 |
20100294362 | Temperature-Control Body for Photovoltaic Modules - Temperature-control bodies for photovoltaic modules have heat transfer tubes embedded in a layer of compressed expanded graphite and connected to the surface of a photoelectric cell layer that faces away from the solar radiation. A layered composite semi-finished product has a layer of compressed expanded graphite with a density of between 0.02 g/cm3 and 0.5 g/cm3. | 11-25-2010 |
20130001475 | MATERIAL COMPOSITION, METHOD OF PRODUCING THE COMPOSITION, AND OXIDATION-PROTECTED MANUFACTURE - A material composition is formed with a carrier component and an additive component. The additive component has one or more ceramic additives. The carrier component and the additive component are present in a ratio by volume in the range from approximately 1:9 to approximately 7:3, preferably in the range from approximately 1:4 to approximately 2:1. More particularly, they are present in a ratio of approximately 1:1. The material composition may be formed as a foil or as a liquid, viscous, paste or gel material. The material composition may be used, inter alia, as oxidation protection and as a sealing element. | 01-03-2013 |
20130032278 | GRAPHITE-CONTAINING MOLDED BODY AND METHOD FOR THE PRODUCTION THEREOF - A graphite-containing molded body is obtained by a method in which graphite particles are mixed with at least one solid additive to form a mixture which contains at least one inorganic additive, a mixture consisting of an inorganic additive and an organic additive, or more than 10 wt. % of an organic additive and the thus obtained mixture is subsequently compressed. The at least one additive which is used contains particles having an average diameter of between 1 and 500 μm, determined in accordance with the ISO 13320 standard. | 02-07-2013 |
20130040194 | LAYERED COMPOSITE MATERIAL FOR USE IN A REDOX FLOW BATTERY - A layered composite material which is suitable, in particular, for use in a redox flow battery, contains at least one layer of a textile fabric and at least one graphite-containing molded body which is obtained by a method in which graphite particles are mixed with at least one solid organic additive to form a mixture and the thus obtained mixed is then compressed. | 02-14-2013 |
20130199412 | METHOD FOR PRODUCING A MOLDED PART FROM A CARBON MATERIAL USING RECYCLED CARBON FIBERS AND MOLDED PART - A method produces a molded part from carbon containing carbon fibers in an amount of less than 20% by weight. The method includes comminuting waste parts or scrap parts formed from a carbon fiber-reinforced synthetic material, a carbon fiber reinforced carbon or a carbon fiber reinforced concrete. A mixture is produced from the comminuted product, a binder such as pitch, a carbon material such as coke and optionally one or more additives, wherein the mixture contains less than 20% by weight of fibers. The mixture is molded into a molded part and the molded part is carbonized. Optionally, the molded carbonized part is impregnated with an impregnating agent. Finally and optionally, the molded carbonized part or the molded part impregnated part is graphitized. | 08-08-2013 |
