Definitions
- the invention relates to an electrical conductor from etched Tape material based on molybdenum yttrium oxide as Power supply in lamps with metal / glass seal.
- Lamps include, in particular, halogen lamps and Discharge lamps, such as high-pressure mercury lamps, Metal halide lamps and xenon high-pressure discharge lamps.
- molybdenum conductor Further material requirements for the molybdenum conductor are Ductility, good ductility, high mechanical strength, Resistance to oxidation and corrosion, especially against halides, and weldability with other conductor components.
- DE-C-29 47 230 has created an electric lamp with a mechanically firmer lead-through to the task and describes, instead of the previously used Molybdenum foil to use one in which in the molybdenum Yttria particles in an amount of 0.25 to 1% of Molybdenum weight are dispersed.
- This material shows however, measured against today's requirements, inadequate Corrosion, especially oxidation properties.
- DE-C-30 06 846 proposes the electrical Conductor for carrying electricity in the form of a molybdenum or Tungsten foil with a second metal from a group case made of tantalum, niobium, vanadium, chrome, zircon, Titanium, yttrium, lanthanum, scandium and hafnium.
- the Cladding of the molybdenum or tungsten conductor can according to Patent by evaporation, sputtering, electrolysis and other procedures take place.
- the sheathing represents a complex, cost-intensive process and guarantees at economic implementation not as uniformly thick Application that the desired in all areas Corrosion protection is ensured.
- US-A 5 021 711 also deals with that Protection against oxidation of molybdenum foils used as electrical Ladder used in vacuum lamps and suggests that Molybdenum foil on the surface with ion implantation Chromium, aluminum or combinations of these metals too refine.
- the lack of insufficient weldability hits to and this process is complex for this material and expensive. It increases the manufacturing cost of the mass product Quartz lamp to an unsatisfactory extent.
- EP-B-0 309 749 is concerned with increasing the Oxidation resistance of molybdenum used in electrical Use lamps in the sealing area as electrical conductors should find.
- EP-B-0 098 858 proposes to increase the Resistance to oxidation, but also weldability and Resistance to hydrogen-containing media before Covering a molybdenum power lead with a To provide rhenium layer.
- Rhenium is an expensive material.
- the known methods for producing the coating are expensive, so that the main disadvantage in the lack of economy of such treated electrical conductor lies.
- a molybdenum alloy for an electrical conductor as a power supply for lamps, consisting of 0.01 to 5% by weight of one or more oxides of lanthanides, the remainder being Mo.
- this material has excellent weldability and high-temperature strength compared to other known conductor materials, other application-specific material characteristics are less favorable than for individual ones of the previously known Mo alloys.
- the sum of all material properties recommends use as a wire-shaped power supply for tempered glass melts, but not as a tape or film for quartz glass melts.
- JP-B-60058296 describes a heat-resistant alloy from 10 to 70% by weight of yttrium oxide and / or cerium oxide, the rest Molybdenum used for thermowell protection tubes becomes. A suitability of this alloy for power supply in Lamps cannot be found in this prior publication.
- the above-mentioned object is surprisingly achieved by an electrical conductor in the embodiment according to claim 1.
- Lamps according to the present invention include various types of incandescent halogen lamps as well as discharge lamps such as e.g. B. high-pressure mercury lamps, high-pressure xenon lamps and metal halide lamps.
- the strip material is used in a wide variety of dimensions in the lamp, but in particular as a thin, elliptically etched foil.
- the electrical conductors according to the invention can be used without restriction while maintaining the currently customary methods for lamp production, in particular the metal / glass melting or squeezing technique. This also applies in particular to methods according to which the ends of the electrical current conductor according to the present invention are welded to further current-carrying components and, including the welded connections, melted or squeezed into quartz glass.
- etching agents and etching processes customary today for molybdenum tape material or molybdenum foils are used. This applies in particular to the widespread methods for thinning the lateral edge zones of a conductor strip.
- the following examples describe advantageous configurations of the electrical conductor according to the invention and its manufacture. The explanations are supplemented by comparative studies on the oxidation resistance of such electrical conductors.
- molybdenum powder with a finely divided mixture of 0.55% by weight of yttrium-cerium mixed oxide with a ratio of cerium oxide to yttrium oxide of 0.25 was produced by means of liquid doping (oxide particle size ⁇ 0.1 ⁇ m), compacted by die pressing and then sintered at 1850 ° C / 5 h.
- the rolled blanks produced in this way were processed into strips with a thickness of 0.045 mm by means of hot and cold rolling, then cut and brought into the elliptical shape typical of the melting strip using an electrolytic pickling process and annealed at 800 ° C. under a H 2 atmosphere.
- a molybdenum tape material according to the invention 0.55% by weight cerium-yttrium mixed oxide with a ratio of Cerium oxide to yttrium oxide of 0.43, was according to the Manufacturing conditions prepared according to Example 1.

Description
Dieser Werkstoff weist zwar gegenüber anderen bekannten Leiterwerkstoffe hervorragende Schweißbarkeit und Hochtemperaturfestigkeit auf, andere anwendungsspezifische Werkstoffmerkmale sind aber ungünstiger als bei einzelnen, der bereits vorbekannten Mo-Legierungen. Die Summe aller Werkstoffeigenschaften empfiehlt die Verwendung als drahtförmige Stromzuführung für Hartglas Einschmelzungen, nicht aber als Band bzw. Folie für Quarzglas Einschmelzungen.
Als schwerwiegenden Nachteil verursacht dieser Werkstoff häufig Sockelrisse im Glas im Bereich der Einschmelz- bzw. Einquetschzone, verursacht durch Werkstoff-Festigkeitsänderungen im Zuge seiner Rekristallisation während des Einschmelzens.
Die vorbezeichnete Aufgabe wird durch einen elektrischen Leiter in der Ausführung nach Patentanspruch 1 in überraschender Weise gelöst.
z. B. Quecksilberdampf-Hochdrucklampen, Xenon-Hochdrucklampen und Halogen-Metalldampflampen. Das Bandmaterial wird in der Lampe in verschiedensten Abmessungen, insbesondere aber als dünne elliptisch geätzte Folie verwendet. Die elektrischen Leiter gemäß Erfindung können in Beibehaltung der heute üblichen Verfahren zur Lampenherstellung, insbesondere der Metall-/Glas-einschmelz- bzw. -einquetschtechnik, uneingeschränkt verwendet werden. Das gilt insbesondere auch für Verfahren, nach denen der elektrische Stromleiter gemäß vorliegender Erfindung an seinen Enden mit weiteren Stromführungs-Bauteilen verschweißt und einschließlich der Schweißverbindungen in Quarzglas eingeschmolzen bzw. eingequetscht wird.
- geringe Neigung zur Folienabhebung in Quetsch- bzw. Einschmelzdichtungen dank besonders günstiger Oberflächenstruktur des geätzten Leiterbandes
- geringe Neigung zu Folienrissen dank stabiler Feinkörnigkeit des Materials auch nach der Rekristallisation im Zuge der Leiter-Einschmelzung
- Vermeidung von Sockelrissen im Quarzglas dank vergleichsweise niedriger Rekristallisationstemperatur unter 1300°C, mit der Folge geringen Spannungsaufbaus zwischen elektrischem Leitermaterial und Glas.
Die nachfolgenden Beispiele beschreiben vorteilhafte Ausgestaltungen des elektrischen Leiters gemäß Erfindung sowie dessen Fertigung. Die Ausführungen werden ergänzt um vergleichende Untersuchungen zur Oxidationsbeständigkeit derartiger elektrischer Leiter.
Die so hergestellten Walzplatinen wurden mittels Warm- und Kaltwalzen zu Bändern mit einer Dicke von 0,045 mm verarbeitet, danach geschnitten und unter Anwendung eines elektrolytischen Beizprozesses in die für das Einschmelzband typische elliptische Form gebracht und unter H2-Atmosphäre bei 800°C geglüht.
