FIELD: chemistry.SUBSTANCE: invention relates to a method of obtaining a moulded product from a carbon material and can be used as graphite electrodes and connecting elements for electrothermal processes. The method includes the following stages: a) milling production wastes or spoiled products from a composite material reinforced with carbon fibres with sieving dust, with the said material representing a polymer reinforced with carbon fibres, carbon reinforced with carbon fibres or concrete reinforced with carbon fibres; b) obtaining a mixture from the milled product obtained at stage a), a binding substance such as pitch, a carbon material such as coke, and optionally one or several additives, with the said mixture containing less than 20 wt % of fibres; c) moulding the obtained mixture into the moulded product; d) carbonisation of the moulded product. After carbonisation the product can be soaked with a soaking preparation with further graphitisation.EFFECT: increased strength and resistance of the products to temperature changes with the simplification of the method of their production.15 cl, 1 tbl, 9 ex |
