What is the cost of rhenium?
Regarding this, how is rhenium used in everyday life?
Uses of Rhenium Rhenium is used with platinum as catalysts in the production of lead-free, high-octane gasoline. The metal is used in alloys for jet engines and in tungsten and molybdenum based alloys. It is widely used as filaments for mass spectrographs. Rhenium is also used as an electrical contact material.
Subsequently, question is, how Rhenium is obtained? Commercial rhenium is obtained from molybdenum roaster-flue dusts found in copper-sulfide ores. However, rhenium does not occur freely in nature or as a compound in mineral ores. Molybdenum contains from 0.002 percent to 0.2 percent rhenium, and the element is found widely spread through the Earth's crust.
Secondly, is rhenium dangerous?
When it comes to toxicity, the health effects of exposure are insufficiently studied. Exposure may cause respiratory problems, burns, and skin and eye irritation. Overexposure may cause suffocation and dizziness. Some compounds of rhenium have been tested in laboratory conditions and showed low levels of toxicity.
What is the oxidation state of rhenium?
Rhenium compounds are known for all the oxidation states between −3 and +7 except −2. The oxidation states +7, +6, +4, and +2 are the most common. Rhenium is most available commercially as salts of perrhenate, including sodium and ammonium perrhenates. These are white, water-soluble compounds.
