Abstract

PURPOSE: To obtain longer emission life, by preventing enlargement of crystal grains and making stable the cathode even at a high temperature through the increase in mechanical strength, by specifying the amount of metal through the formation of Ni containing Si, Mg, Zr and B for the base metal of electron tube cathode.
