MANUFACTURE OF DISPENSOR CATHODE |
摘要 |
<p>The invention relates to the manufacture of a dispenser cathode having a porous tungsten body incorporating scandium oxide in at least a layer adjacent the surface area intended for electron emission. It was surprisingly found that a scandium oxide-containing tungsten body can be mechanically processed satisfactorily if it incorporates copper prior to the processing operation.</p> |
