  • Rhenium Powder

    Rhenium is grey to black in powder form, silvery-white, and lustrous as a solid. Rhenium Powder has a crystalline structure at temperatures up to its melting point, and it does not exist naturally. Rhenium has one of the highest densities, just less than platinum, iridium, and osmium. Only tungsten and carbon have higher melting points than it. Rhenium has good wear resistance, and it can withstand arc corrosion. Rhenium’s range of valences is higher than other elements. We are a global leader in providing Rhenium chemicals which are used to manufacturer critical parts and components. These are used in high-density, high-temperature parts for aerospace, defence, energy, and X-ray device industries. We supply three standard powders, Rhenium, Molybdenum-Rhenium, and Tungsten-Rhenium.

    Typical Applications of Rhenium Powder

    Rhenium is used in platinum-rhenium catalysts, which are primarily used to make lead-free, high-octane gasoline, and in high-temperature superalloys which are used to make jet engine parts. Other uses:
    1) Widely used as filaments in mass spectrographs and ion gauges.
    2) An additive to tungsten and molybdenum-based alloys to increase ductility in these alloys.
    3) An additive to tungsten in some x-ray sources.
    4) Rhenium catalysts are very resistant to chemical poisoning and are used in certain hydrogenation reactions.
    5) Electrical contact material due to its good wear resistance and ability to withstand arc corrosion.
    6) Thermocouples containing alloys of rhenium and tungsten are used to measure temperatures up to 2200 °C.
    7) Rhenium wire is used in photoflash lamps in photography.
    8) Rhenium forms rhenium diboride with boron.
    9) It is a compound noted for its extreme hardness.
    10) Isotopes of rhenium are radioactive. The 188 isotopes, with a half-life of 69 days, has been tested for the treatment of liver cancer. The 188 isotopes may be obtained in the form of a generator.
    11) Related to periodic trends, rhenium has similar chemistry with technetium. This is useful for radiopharmacy. Because it is expensive and has short half-life, it is difficult to work with technetium - especially the 99m isotope used in medicine.
    12) For use in booster rocket engines
