  • Abstract
    A new kind of cathode, LaC2-Mo cathode was prepared through spark plasma sintering method by using the mixed powder of LaC2 which was prepared by vacuum melting method and molybdenum. It was found that the emission properties of LaC2-Mo cathode increases with the LaC2 content increasing. The emission current density of LaC2-Mo cathode which contains 3.5wt.% LaC2 could reach 0.90A/cm2 at 1400.b whereas that of LaC2-Mo cathode with 10wt.% LaC2 could reach 3.02A/cm2 at 1400.b. Richardson Work function of LaC2-Mo with LaC2 3.5wt% is 2.53eV.
