Abstract:
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.
Abstract:
A nitrogen-emitting composition which is adapted to be used with flash getter materials. Said composition comprising iron, germanium, and nitrogen. These materials are used within cathode ray tubes to produce a getter film which is deposited on the inner walls of the cathode ray tube.
