  • Halogen incandescent lamp
    Patent number: 4361780
    Abstract: In halogen incandescent lamps with bromine as the halogen and having a tantalum getter to absorb any free oxygen, the getter also absorbs bromine at high operating temperatures and affects the tungsten-bromine cycle adversely.Tantalum alloyed with tungsten in a weight ratio range of 9/1 to 1/9 has a very much larger affinity to oxygen than it has to bromine. As a result of this the alloys are excellently suitable for use as an oxygen getter in tungsten/bromine cycle lamps.
