Oxygen-enriched niobium wire

Abstract

A niobium wire, a process for producing it, 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.

1 . (Original) A niobium wire that it is enriched with oxygen.  
     
     
         2 . (Original) A niobium wire in accordance with  claim 1 , wherein the oxygen is in a concentration of about 3,000 to 30,000 μg/g.  
     
     
         3 . (Original) A process for producing oxygen-enriched niobium wire, comprising the steps of: treating niobium in an oxygen-containing atmosphere in a closed chamber at elevated temperature; and drawing the niobium treated in this way into wire.  
     
     
         4 . (Original) A process in accordance with  claim 3 , wherein the treating step is carried out in an atmosphere of air.  
     
     
         5 . (Original) A process in accordance with  claim 3 , wherein the drawing step includes drawing the niobium into wire having a diameter of 0.2-0.4 mm.  
     
     
         6 . (Original) A process in accordance with  claim 3 , wherein the treating step is carried out at temperatures of 600-800° C.  
     
     
         7 . (Original) A process in accordance with  claim 3 , wherein the treating step is carried out at pressures below 5 mbars.  
     
     
         8 . (Original) A process in accordance with  claim 3 , wherein the drawing step is carried out at room temperature.  
     
     
         9 . (Original) Use of oxygen-enriched niobium wire for connection to niobium or niobium oxide capacitors.
