23 Rhenium Uses : Facts You Should Know!

Rhenium is a transition earth metal belonging to group 7 and period 6 of the d-block in the periodic table. Let us learn about the uses of Rhenium.

The industrial uses of rhenium are listed below:

  • Alloys
  • Catalyst
  • Electronics
  • Chemical synthesis and reactions
  • Nanoscience
  • Electrochemistry


  • Rhenium is used to make alloys and superalloys. Rhenium-tungsten alloys are very ductile and can bear high temperatures.
  • Re and platinum alloys are mixed in petroleum refineries to convert oils with low octane to high octane ratings.
  • Re is a substitute for technetium alloys because of their similar chemical properties and Re is cheaper than technetium.
  • Rhenium-tungsten and rhenium-molybdenum alloys are used in alloys that are used in x-ray machines and oven filaments.
  • The alloys of rhenium works as electrical contact materials because they are resistive to corrosion and have less wear and tear.
  • Rhenium is mixed with nickel to form alloys that are used in the making of turbine blades.


  • Rhenium pentachloride (Re2Cl10) is not found commercially, but it was used as a catalyst in metathesis reactions in earlier ages.
  • Rhenium trioxide (ReO3) is a hydrogenation catalyst used in amide reduction in organic chemistry.
  • Rhenium oxide is used as a catalyst for only some specific reactions and conditions.


  • ReO3 exceptionally has higher electrical conductivity when compared to other oxides.
  • Rhenium hexafluoride is employed commercially in the electronics industry to deposit rhenium films on electronic parts.
  • ReSe2 is potentially applied in electronics, semiconductors, thermoelectric and lasers due to its unsymmetrical lattice structure.
  • Rhenium disulfide (ReS2) is used in electronic and optoelectronic devices.

Chemical synthesis and reactions

  • Re2O7 works well in alkene metathesis and the formation of bis-peroxy acetals.
  • Rhenium heptafluoride is used in the oil refining and etching process.
  • Rhenium heptafluoride can produce several synthetic compounds in organic chemistry.
  • Tri-rhenium nonachloride (Re3Cl9) works as a base material for the producing other rhenium compounds.
  • ReBr4 is used in water treatment and crystal growth processes.
  • Rhenium(VII) oxide is employed as a reagent of dehydration.
  • Rhenium(VII) oxide (Re2O7) is found during the rearrangement of alcohols, amides, oximes and oxidative cyclization.
  • Re is widely applied in the alkylation of organic compounds, reforming of petroleum feedstock and metathesis of alkenes.


  • Rhenium diselenide is used to prepare ReSe2 nanoparticles and nanosheets of a few layers.
