The process was so complicated and the cost so high that production was discontinued until early 1950 when tungsten-rhenium and molybdenum-rhenium alloys were prepared. These alloys found important applications in industry that resulted in a great demand for the rhenium produced from the molybdenite fraction of porphyry copper ores.

· Atomic mass of Rhenium is 186.207 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or ...

Rhenium is one of the rarest elements in Earth's continental crust; its estimated average crustal abundance is less than 1 part per billion. Rhenium is a metal that has an extremely high melting point and a heat-stable crystalline structure. More than 80 percent of the rhenium consumed in the world is used in high-temperature superalloys, especially those used to make turbine blades …

An unsupported uranium–rhenium bond has been prepared by alkane elimination by treatment of a cyclometallated alkyl uranium triamidoamine complex with rhenocene hydride (see scheme). DFT analysis reveals σ and π combinations in the U Re bond, but the rhenium contributions dominate and an atoms-in-molecules analysis reveals a closed-shell, predominantly ionic …

· Thus, the average Re/U3O8 ratio on the resin, fully loaded in both rhenium and uranium, was 0.0116. A sample of Amberlite IRA-425 resin from the Palangana pilot plant was used to evaluate the effectiveness of various rhenium eluting agents. The resin sample as received had a rhenium loading of 320 mg/L (0.020 lb/ft³).
