摘要 |
A sintered electrode in a discharge tube comprises a sintered compact body and a cesium compound layer deposited on the sintered compact body. The sintered compact body comprises a gas getter such as titanium in the range of 5 to 50% by weight of the body, an additive for sintering such as silicon oxide in the range 0.1 to 1.0% by weight of the body and the remainder formed by a high melting point metal such as tantalum.
