The followinguses 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 additionalreferenced 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
