Single La2O3, Ce2O3 doped Mo with low content of RE2O3 has good thermionic emission property. The zero-field emission current densities at 1450 degC of 6.87A/cm and 5.03 A/cm2 could be obtained for La2O3(4wt%)-Mo and Ce203(4wt%)-Mo, respectively.La2O3-Mo, Ce2O3-Mo cermet cathode containing high content of RE2O3 shows a certain secondary emission property. A layer of RE2O3 could be formed at surface...
Secondary emission has been used in many fields stimulated by the development of vacuum electronic technology, especially in the field of high power magnetron. The development of high power magnetron needs cathodes which could provide high secondary emission yield (Vasilyva, 1996). As a novel cathode which is expected to be applied in magnetron, CeO2-Y2O3-Mo cermet cathode has be prepared by liquid-liquid...
