(1) Artificial graphite (electrographite) is a type of carbon, usually prepared in an electric furnace by heating a mixture of finely milled coke (usually petroleum coke, but sometimes anthracite, retort, bakery coke, etc.) and carbon binders (for example, peck or tar) at a sufficiently high temperature (2500 – 3200 ° C) to ensure their “graphitization” under the catalytic influence of substances present in the mixture (for example, silica or iron oxide). First.

the mixture is extruded or pressure-moulded into "green" blocks of square or circular cross-section. These blocks may be pre-baked at a temperature of about 1000 °C and then "graphitised", or they may be obtained directly in the graphitisation process. The product thus obtained has an apparent specific gravity of about 1.5 – 1.6 and a homogeneous microcrystalline structure, X-ray examination of which shows that it is graphite. Chemical analysis confirms that this substance is graphite (precipitation of graphitic acid). In addition to the usual grades of artificial graphite, this heading covers: (a) Artificial graphite for nuclear reactors, which is a specially prepared graphite with a boron content not exceeding one part per million and a total thermal neutron absorption cross-section not exceeding 5 millibarns per atom. This grade has a very low ash content (not exceeding 20 parts per million) and is used as a moderator or reflector in nuclear reactors. (b) Impregnated or impermeable artificial graphite, i.e., artificial graphite which, in order to increase its apparent specific gravity or its impermeability to gases, is first impregnated under vacuum with tar or resins, or with solutions of sugars or other organic products, and is then re-baked to graphitise the carbonaceous residues of these additives. The impregnation process may be repeated several times to obtain a higher apparent specific gravity (1.9 or more) or a greater degree of impermeability. Impregnated graphite may also be used for nuclear reactors. The artificial graphite of this heading is usually produced in the form of powder, flakes, blocks, plates, bars, rods, etc. Blocks and plates are used, after cutting and high-precision machining (close tolerances and proper surface finish), for the manufacture of brushes or other graphite electrical articles of heading 8545, or of parts of nuclear reactors. This heading also covers scrap, waste and worn-out articles, usable only for the recovery of artificial graphite. The heading excludes: (a) Natural graphite (heading 2504); (b) Retort carbon (or gas carbon), sometimes incorrectly called "artificial graphite" (heading 2704); (c) Artificial graphite with a worked surface or a finished surface, cut into special shapes, turned, drilled, milled, etc., or specially formed into articles. Articles not for electrical purposes generally fall in heading 6815 (e.g., filters, discs, bearings, moulds, acid-resisting blocks, etc.); articles for electrical use fall in heading 8545; (d) Refractory articles based on artificial graphite, fired as ceramics (heading 6902 or 6903); (e) Blocks, plates, bars and similar semi-manufactures of artificial graphite which also contain silver powders (heading 7106). (2) Colloidal or semi-colloidal graphite. (a) Colloidal graphite is finely divided natural or artificial graphite in the form of a colloidal suspension in water or in another medium

(e.g., alcohol, mineral oil), to which small quantities of other products, such as tannin or ammonia, may be added to stabilise the suspension. Colloidal graphite is usually semi-fluid and is used mainly in the manufacture of lubricants or where its high electrical conductivity is required. (b) Semi-colloidal graphite (i.e., graphite in the form of a semi-colloidal suspension in water or in other media). Semi-colloidal graphite may be used in the manufacture of graphited oils or for forming graphitised surfaces. This heading covers only graphite in colloidal or semi-colloidal suspension in any medium, where graphite is the principal constituent. (3) Products based on graphite or other carbon, in the form of pastes, blocks, plates or other semi-manufactures. (a) "Carbon" blocks, plates, bars and similar semi-manufactures, of the metal-graphite or other types. These terms refer to a group of semi-manufactures, such as blocks, plates, etc., which are used for the manufacture of "carbon" brushes for electrical and electrotechnical equipment or apparatus and which are based on carbonaceous materials (alone or combined with other substances). These semi-manufactures are generally divided into the following types: (i) "carbons" obtained by baking, at a temperature (1000 – 1200 °C) insufficient for true "graphitisation", mixtures of finely ground coke or lamp black and natural powder or artificial graphite with carbonaceous binders such as pitch or tar. The structure of the products thus obtained is heterogeneous; microscopic examination reveals the presence of a mixture of graphite grains with grains of amorphous carbon, and chemical analysis shows that the precipitate of graphitic acid is smaller than in the case of artificial graphite; (ii) compositions of the metal-graphite type, obtained by a process similar to sintering (agglomeration, moulding and baking) from mixtures of powdered graphite with powders of base metals (copper, cadmium or their alloys). Their metal content ranges from 10 to 95 %; (iii) goods obtained by moulding natural or artificial graphite powder mixed with plastics. Blocks and plates obtained, in particular, from the materials mentioned above are usually of about 200 x 100 x 35 mm or 150 x 70 x 30 mm. After cutting and careful machining (close tolerances and appropriate surface finish), they are used mainly for the preparation of electric brushes of heading 8545. The above-mentioned semi-manufactures, if they contain powdered silver, fall in heading 7106. This heading also excludes blocks cut to special shapes, with a worked surface, finished surface, etc. (generally heading 6815 or 8545), and refractory articles fired as ceramics, based on amorphous carbon or natural graphite (heading 6902 or 6903). (b) Carbon pastes for electrodes. These products consist mainly of a mixture of anthracite and coal tar (which acts as a binder). They are usually presented in the form of small blocks which are placed in the upper part of a metal container, where they soften under the action of heat. Thus they

Thus, they are molded inside the container and form an infinite electrode when used in furnaces that do not need to be stopped to replace used previously manufactured electrodes. The most famous composition of this type is "Soderberg paste". Similar pastes are used for lining furnaces so that the refractory coating hardens in situ. This also includes graphite in the form of a paste consisting of a mixture of graphite in the form of particles (mostly more than 5 μm) with mineral oils and equally the accelerator of one for the treatment of surfaces of heavy equipment or for the manufacture of graphite lubricants.
