  • Discovery Year: 1925
  • Name Origin:
    Greek, Rhenus for the Rhine River.
  • Abundance of Rhenium:
    • Earth's Crust/p.p.m.: 0.0004
    • Seawater/p.p.m.: 0.000004
    • Atmosphere/p.p.m.: N/A
    • Sun (Relative to H=1E12): 2
  • Sources of Rhenium:
    Found in small amounts in gadolinite and molybdenite. It is usually extracted from the flue dusts of molybdenum smelters. Annual world production is around 4.5 tons.
  • Uses of Rhenium:
    It is added to tungsten and molybdenum alloys and is used in refractory metal components of missiles, electronic filaments, electrical contacts, high-temperature thermocouplers, oven filaments, electrodes, igniters for flash bulbs, jewelry, plating of metals by electrolysis and vapor-phase deposition.
  • Additional Notes:
    Rhenium is a metallic element that has a very high tensile strength (80,000psi), high modulus of elasticity, is virtually insoluble in hydrochloric acid and does not oxidize or corrode in saltwater. In addition it has the widest range of valences of any element and it retains its crystalline structure all the way to its melting point. Alloys of rhenium-molybdenum are superconductive at 10K.
