Electric discharge lamp having a cathode with cesium metal oxide |
摘要 |
A discharge type electric lamp construction is described having electrode means which include a porous sintered body of refractory metal having an electron emissive material containing cesium ion dispersed in the pores of said porous sintered body as Cs2MO4 wherein M is a refractory metal. Said electron emissive material is preferably employed in combination with another electron emissive material containing barium ions to provide a lower breakdown voltage as well as operating voltage characteristics for said discharge lamps. Representative electron emissive materials containing barium ions include barium aluminate and barium tungstate materials.
