Rhenium - Element information, properties and uses ...

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.

Rhenium Re - PubChem

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 alloys were prepared.

Concerning Sigma-Phase in Molybdenum-Rhenium Alloys ...

Molybdenum-rhenium alloys containing 40 to 48% Re by weight are commonly used for many high-technology applications. Higher rhenium contents bring the alloys into a two-phase region with the presence of brittle o-phase, an intermetallic compound with the approximate composition of Mo 2Re3. Alloys with lower rhenium contents do not possess sufficient low-temperature ductility and high ...
