Abstract (en)

[origin: EP0756312A2] The electrode (12,14) has at least one heat sink body (26,28) of a metallic material with a high melting point, combined with the electrode via a powder metallurgical process. Pref. the heat sink body is formed from a tungsten and/or molybdenum powder, containing a sintering additive, e.g. crystalline nickel, palladium and/or platinum, which is pressed into contact with the outside of the electrode and sintered .
