Method of Making a Cathode from Tungsten Powder.

Abstract

This invention relates in general to a method of making a cathode for operation in microwave devices and in particular to a method of making a cathode for operation in microwave devices from tungsten powder using as an impregnant the product formed from adding about 1 mole of a member selected from the group consisting of zirconium, zirconium dioxide, hafnium, hafnium dioxide, uranium, uranium dioxide, titanium, and titanium dioxide to about 50 to about 100 moles of a compound selected from the group consisting of Ba3A12O6, Ba3WO6, and Ba4A1207.
