The analysis of the shortcomings of tungsten carbide electrodes manufacturing by remelting furnaces resistivity followed by termotsentrobezhnym spray. The formation of the double tungsten carbide (WC+W2C) in hot pressing a mixture of crushed relite and relite and tungsten and carbon is studied. It is shown that at a temperature of ~ 1900ºC pressing emerging billet electrode with the necessary structural characteristics, tungsten is fully transferred in carbide and semicarbide with the same space group of the crystal lattices as in relite.
