Method of Making a Long Life High Current Density Cathode from Tungsten and Osmium Powders Using Barium Osmiate as an Impregnant.
Abstract
A long life high current density cathode is made from a mixture of tungsten and osmium powders by processing the mixture of powders with an activator into a porous billet, and then impregnating the billet with a barium osmiate by firing the billet in a dry hydrogen furnace at a temperature at which the impregnant melts.
