Abstract: 782,287. Cathode material and processing. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 22, 1955 [March 1, 1954], No. 5219/55. Drawings to Specification. Class 39(1). An air-stabilized barium oxide, especially suitable for cathodes of fluorescent lamps, consists of a mixture of barium oxide and barium zirconate, with the barium oxide portion of each particle encased in a shell of the barium zirconate. Such a material shows comparatively little gain in weight when exposed to air and requires a lower forming and activating current while liberating less gas ; curves are given to illustrate these effects. The material is prepared by heating barium oxide and zirconia, or compounds producing these, at 1200-1500C. in air until all the zirconia is converted into zirconate ; two hours at 1200C. and one hour at 1500C. are typical times. The starting materials may be barium carbonate or, preferably, the hydroxide, with zirconium metal, oxalate, nitrate or, preferably, dioxide. The proportion of zirconate in the finished product may be 1-20 per cent, preferably 10 per cent. The air-stabilized barium oxide may be mixed strontium and/or calcium oxides, a preferred mixture containing 30 per cent strontia and 10 per cent calcium oxide. The material is suspended in nitrocellulose dissolved in an acetate of ethylene glycol monoethyl ether and the tungsten lamp electrode, which may be a single, double, or triple coil, dipped in the mixture until say 4 mg. is taken up.

The substrate may be quartz or alumina, sapphire, ferrite or glass. The protective layer may include at least one of copper, aluminium, chromium, nickel-chromium alloy, nickel, and gold. The material to be deposited on the selected area may include at least one of silicon dioxide, silicon monoxide, alumina, yttrium oxide, silicon nitride, tantalum pentoxide. The method may be used to make microwave capacitors. In the embodiment a gold electrode is deposited on a quartz substrate using a photolithographic technique and a protective layer of copper is deposited by evaporation over the whole surface of the substrate. A layer of photoresist is applied over the copper layer by dip coating and after allowing volatile solvents to evaporate the product is baked. The photoresist is then exposed through an optical mask, developed and the remaining photoresist baked. The copper is then etched away where revealed through the development of the photoresist using as etchant ferric chloride aqueous solution. A layer of silicon dioxide dielectric is then deposited by sputtering in argon and then the remaining photoresist is removed by soaking in acetone the remaining copper etched away in ferric chloride. Another gold contact is then deposited using a photolithographic technique and this contact and the unprotected area of the low electrode are then electroplated. The edge profile of the dielectric depends upon the etching time.
