Rhenium | Re PubChem

Rhenium (Re), the last naturallyoccurring element to be discovered, was discovered in Germany in 1925. The process was so complicated and the cost so high that production was discontinued until early 1950 when tungstenrhenium and molybdenumrhenium alloys were prepared.

Rhenium–osmium dating Wikipedia

RheniumOsmium dating is a form of radiometric dating based on the beta decay of the isotope 187 Re to 187 normally occurs with a halflife of × 10 9 y, but studies using fully ionised 187 Re atoms have found that this can decrease to only 33 y. Both rhenium and osmium are strongly siderophilic (iron loving), while Re is also chalcophilic (sulfur loving) making it useful in ...

METHOD OF FORMING TANTALUM SILICIDE ON TANTALUM …

Abstract. A method is described for forming a noncorrosive silicide coating on tantalum. The coating is made through the heating of trirhenium silicides in contact with the tantalum object to approximately 1400 deg C at which temperature trirhenium silicide decomposes into rhenium and gaseous silicons.

By using two independent methods of determining shear stress at room temperature, it is found that rhenium is one of the strongest polycrystalline materials investigated so far, with shear stress at high pressures reaching tau/mu = + or relative to the shear modulus mu. These values are compatible with current theoretical expectations.
