Method of Making Long Life High Current Density Cathode from Tungsten and Iridium Powders Using a Low Melting Point Impregnant.
Abstract
A long life high current density cathode is made from a mixture of tungsten and iridium powders by processing the mixture of powders with an activator into a porous billet, and then impregnating the billet with a low melting point impregnant by firing the billet in a dry hydrogen furnace at a temperature at which the impregnant melts. Patent applications. (mjm)
