Abstract: The porous material adapted for making a tool-electrode therefrom features the porosity up to 15 - 25 percent of its volume, pore size within 10 to 40 microns and oxygen content up to 0.1 wt.%.The method proposed for producing such a material resides in hot compression moulding of a powdery electrode material. The powdery material is first heated in a compression mould to a temperature equaling 0.3 to 0.5 of the melting temperature in degrees centigrade while pumping a gaseous reducing agent therethrough at a pressure of 1.2 - 1.8 atm, whereupon the powdery material is held for some lapse of time at that temperature, while continuing to feed said reducing gas in a quantity exceeding the stoichiometric one. Next the powdery material is heated to a temperature in degrees centigrade equal to 0.6 to 0.9 of the melting temperature, and a pressure is applied thereto to obtain the required porosity of the material being prepared.
