METHOD OF PRODUCING CARBON GRAPHITE PRODUCTS
The invention relates to the production of carbon items, namely to a technology of their processing during firing, and can be used in various branches of technology for the manufacture of electrodes, crucibles, heaters, as well as materials for nuclear engineering, for example, uranium-graphite fuel elements. In the method for producing carbon-graphite items, comprising placing workpieces in a container with a fill and firing them in an air atmosphere, according to the invention, the fill of the container is urea which is loaded in an amount of 5-10 wt.% of the workpieces. The container is placed in a closed vessel with limited access of air which is filled with a carbon fill also containing urea in an amount of 5-10 wt.% of the fill. The object of the invention and the technical result achieved by using the invention is simplification of the firing process and improvement of the quality of carbon-graphite items, especially small-sized ones, due to the exclusion of their oxidation and coking up of the fill.
