Rhenium - 75Re: uses
The following uses for rhenium are gathered from a number of sources as well as from anecdotal comments. I would be delighted to receive corrections as well as additional referenced uses.
- additive to tungsten and molybdenum-based alloys to impart useful properties
- filaments for mass spectrographs and ion gauges
- rhenium-molybdenum alloys superconduct at 10K
- electrical contact material, as it has good wear resistance and withstands arc corrosion
- thermocouples made of Re-W are used for measuring temperatures up to 2200°C
- rhenium wire is used in flash lamps for photography
- rhenium catalysts are exceptionally resistant to poisoning from nitrogen, sulphur, and phosphorus, and are used for hydrogenation of fine chemicals, hydrocracking, reforming, and the disproportionation of alkenes
