摘要：
Impregnated rare earth metal-containing barium-aluminum-scandate cathodes with a rare earth oxide doped tungsten matrix and methods for the fabrication thereof are described. In one aspect, an impregnated rare earth metal-containing barium-aluminum-scandate cathode comprises: a rare earth oxide doped tungsten matrix, and an impregnated active substance. The active substance comprises scandium oxide (Sc2O3), a second rare earth oxide, and barium calcium aluminate, wherein the molar ratio of Ba:Ca:Al is about 4:1:1.
