<p>FIELD: nonvaporizing getter alloys. SUBSTANCE: nonvaporizing getter alloy contains zirconium, cobalt and one or several components A selected from group including yttrium, lanthanum or rare-earth metal. In this case content of alloy components expressed in weight per cent is comprised in polygon on triple alloy diagram governed by 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. Alloy possesses properties of sorption of various gases having comparatively low activation temperature and applicable in production of heat-insulating vessels such as thermoses, Dewar flasks, or pipeline for transportation of oil, cleaners of inert gases or lamps. EFFECT: production of nonvaporizing getter alloys widely used and safe for environment. 16 cl, 10 dwg, 1 tbl, 8 ex</p> |
