| Discovery | Discovered in 1925 by Walter Noddack, Ida Tacke, and Otto Berg in Germany |
|
Origin of Name |
Derived from the Latin word Rhenus, which stands for the Rhine River in Western Europe. |
| Isotopes | Stable Isotope: Re-185 (37.4% of natural rhenium) Radioactive Isotope: Re-187 (62.6% of natural rhenium, half-life of 4.35 billion years) Other Isotopes: 43 isotopes, all radioactive with short half-lives |
| Source | Mainly extracted as a byproduct of copper mining, found in molybdenite ore (copper sulfide ores) |
| Production Method | Produced from ammonium perrhenate by reduction with hydrogen at high temperatures; can also form various compounds, including oxides and organometallics |
|
Uses |
Rhenium is used in turbine blades for jet engines. Essential for refining lead-free gasoline, hydrogenation of fine chemicals, and hydrocracking in petroleum refining. |
|
Flammability and Explosibility |
Nonflammable |
| Catalyst Resistance | Resistant to poisoning from nitrogen, sulfur, and phosphorus |
