Abstract: An emissive electrode of the type utilized in fluorescent lamps and a method for making such an electrode. The electrode includes a fused cylindrical pellet and two metal leads, a portion of one of said leads extending within one end of said pellet and a portion of the other of said leads extending within the opposite end of the pellet. The pellet contains a fused mixture of electron emissive material and a metal having a high melting point and a low vapor pressure, and it has a bulk density gradient structure. The heat necessary to cause thermionic electron emission from said electrode is provided by current passing through the pellet structure separating said leads when a voltage is applied across said leads. The pellet is formed by mixing a powder of said metal with a powder of said electron emissive material, adhering said powder particles one to the other, and heating said mixed powder in a mold until an exothermic reaction occurs.
Abstract translation: 用于荧光灯的发射电极和制造这种电极的方法。 电极包括熔融圆柱形颗粒和两个金属引线,一个所述引线的一部分在所述颗粒的一个端部内延伸,另一个所述引线的一部分在颗粒的相对端延伸。 颗粒包含电子发射材料和具有高熔点和低蒸气压的金属的熔融混合物,并且其具有体积密度梯度结构。 当电压跨过所述引线施加电压时,通过电流通过分离所述引线的芯片结构来提供从所述电极引起热离子电子发射所需的热量。 通过将所述金属的粉末与所述电子发射材料的粉末混合,将所述粉末颗粒彼此粘合,并将所述混合粉末在模具中加热直到发生放热反应来形成颗粒。
