Abstract

A method for producing carbon items. 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.
