Abstract:
In a halogen-metal vapor lamp having a ceramic housing (2) and a current lead-through conductor (3) arranged in the ceramic housing, the glazed part of the current lead-through conductor (3) is a niobium alloy doped with phosphorus, in particular with 50 ppm to 0.5 wt. % phosphorus. The glazed part of the current lead-through conductor (3) preferably has inside the ceramic vessel (2) a shielding (4) from halides, which is connected to a tungsten electrode. The glazed part of a current lead-through conductor (3) in the form of a pin having a length of 5 to 30 mm and a diameter of 0.2 to 2 mm is a niobium alloy doped with phosphorus. For the glazing of current lead-through conductors in a ceramic burner, a current lead-through conductor made of a niobium alloy temperature-stabilized with phosphorus is glazed. For the production of halogen-metal vapor lamps having a ceramic housing (2) and a current lead-through conductor (3) arranged in the ceramic housing (2), the current lead-through conductor (3) is exposed to heat treatments at temperatures of at least 1000° C. and there does not soften so much that it bends.

Abstract:
A process for providing a niobium wire and its use for connection to niobium or niobium oxide capacitors. The wire is enriched with oxygen and preferably has oxygen concentrations of about 3,000 to 30,000 μg/g.
Abstract:
A highly heat resistant wire based on niobium or tantalum or niobium tantalum alloy for single-side socket lamps is enriched, according to the invention, with phosphorus and converted into an annealed state. The wire exhibits a yield strength Rp 0.2 of at least 200 MPa or a tensile strength Rm of at least 300 MPa. For the production of a frame for single-side socket lamps, a metal based on niobium or tantalum or an alloy thereof is doped with phosphorus and the doped metal is cold shaped into a wire, this wire is annealed and formed into a frame. This frame is used for the simultaneous current supply and holding of a burner in a single-side socket lamp.
