Rhenium

Rhenium is both highly siderophile (see entry for " Siderophile Elements ") and strongly chalcophile (see entry for " Chalcophile Elements " ) and is grouped with other 5th and 6th row transition metals having similar chemical properties: Ru, Rh, Pd, Os, Ir, and Pt; the so-called platinum group elements (PGE; see entry for " Platinum Group Elements " ).

Rhenium

In fact a combination of rhenium and platinum make up the catalyst of choice in the very important process of making lead-free and high-octane petrol. Rhenium catalysts are especially resistant to chemical attack from nitrogen, phosphorus, and sulfur, which also makes them useful in hydrogenation reactions in various industrial processes.

Iridium, Osmium, and Rhenium Plating. Electrodeposition

If Rhenium traps hydrogen like platinum or palladium you need to know this and you'll want to operate without a huge overpotential. Next, determine the pH of your solution. The anodes are typically left in the solution so you need to have a feel for their corrosion resistance requirement. Get price

Rhenium Statistics and Information

Rhenium (Re), the last naturally-occurring 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 tungsten-rhenium and molybdenum-rhenium Get price

Rhenium – Discovery, Properties, Isotopes and Uses

Only 1 stable isotope is noted for Rhenium which is rhenium-185. Again, this is the rarest isotope ever and is sometimes observed in the metallic elements Tellurium and Indium. A total count of 33 isotopes are recognized for Rhenium, that ranges from 160 Re to 194 Re, all of them termed to be unstable and 183 Re is the longest-present isotope among all with a half-life of 7- days.
