Abstract: An improved scandate cathode is made from a hollow cylinder of a metal that ill not react with Sc.sub.2 (WO.sub.4).sub.3. The first step in making such a cathode is to insert a metal plug at the bottom of the cylinder to a height that will allow the remaining volume of the cylinder to be filled with the reactants WO.sub.3 and Sc.sub.2 O.sub.3. Next, the reactants are heated in a vacuum to about 1100.degree. C. to form the reaction product Sc.sub.2 (WO.sub.4).sub.3. The plug is then removed from the cylinder, the cylinder is inverted, and BaH.sub.2 is added to the volume of the cylinder that had been occupied by the plug. Finally, the cylinder is heated to decompose the BaH.sub.2.
