An electrode for an electron gun and an electron gun using same are provided
which
make use of stable carbon material having small work function and which permit
orientation control to be achieved and which can be manufactured at a low cost.
An electrode for an electron gun uses carbon electrode(s) formed from amorphous
carbon and carbon nanotubes or carbon nanofibers and molded in linear shape. The
carbon electrode is obtained by mixing a resin composition such as chlorinated
vinyl chloride resin, furan resin, etc., which forms non-graphitizing carbon after
carbonizing, with a carbon powder such as carbon nanotubes or carbon nanofibers
and, after extrusion, molding and carbonizing the molding obtained.
