An electrode for a plasma arc torch and method of fabricating the same a re disclosed, and wherein the electrode comprises a copper holder defining a cavity in a forward end. An emissive element and separator assembly is positioned in the cavity. The emissive element is formed from the powders of at least two materials, a nd the separator includes a material that is substantially similar to one of the materials forming the emissive element. The emissive element is heated and a plurality of thermal conductive paths are formed that extend from within the emissive element to the separator that improve the thermal conductivity of the electrode.</SDOAB >
