    • Abstract
  • Powder rolling-sintering process for producing high pure nickel porous foils has been studied. The properties of the storage-type oxide cathode materials made by porous nickel and its applications in EY-501 type travelling-wave tube have bean investigated. Powder rolling-sintering process exhibits advantages of simple process, high yield of finished products, low production costs and suitability for large scale production when it compared with those of photo mesh engraving method. In addition, it also has features of anti-toxicity,long performance durability and the coincidence of electronic emission.
