Abstract
An appreciable increase in thermionic emission from oxide coated filaments has been obtained by introducing a small percentage of metallic barium (approximately 0.15 percent) into the nickel core material. Comparisons made on the electron emission of this alloy with pure nickel and also with the nickel alloy after the barium had been extracted always showed the influence of barium in the base metal.Keywords
