Abstract

755,804. Discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 27, 1954 [Sept. 30, 1953], No. 27818/54. Class 39 (1). In a method of producing a non-vaporizing getter in which the gas-absorbing constituent consists substantially of one or more of the refractory metals capable of forming non- gaseous hydrides (e.g. zirconium, thorium, titanium, tantalum, niobium, and vanadium), said metal is powdered, and mixed and compressed with an additional constituent consisting of aluminium, silicon, or beryllium, or a powdered alloy of one or more of these with cerium, lanthanum, or misch metal; the compressed mass is then mounted in a vacuum vessel and activated by heating. If zirconium is used as a starting material, it may be mixed with tungsten to prevent it initially sintering to compactness. The zirconium may be introduced in the form of the hydride. Titanium (if not initially present), or iron, or nickel, may also be added to bind the additional metal. Examples are given, specifying suitable proportions, of Th+Ce+A1; Zr+A1; Th+Ce+Si; Zr(hydride)+Ti+Al; Zr+Al+Ni(+Ti); Zr+ W+Al+Ni; Zr+Ta+Al+Ni. Other mixtures mentioned are Th+Al+Ni; Ti+Al+Ni; Zr+Al+Fe; Zr+W+Al+Ti.
