Abstract:
Non-evaporable getter (NEG) alloys comprising zirconium, cobalt and one or more components selected among yttrium, lanthanum or rare earths such that, in the ternary diagram of weight % compositions, they are enclosed in the polygon defined by the points: a) Zr 81% - Co 9% - A 10%; b) Zr 68% - Co 22% - A 10%; c) Zr 74% - Co 24% - A 2%; d) Zr 88% - Co 10% - A 2%. wherein A is any element selected among yttrium, lanthanum, rare earths or mixtures thereof. They may be activated at relatively low temperatures and are capable of sorbing a wide variety of gases. Furthermore, the alloys of the invention are safer from the environmental and safety point of view with respect to other similar alloys, in that not containing metals which are toxic or capable of forming toxic compounds.
