Fast ein Jubiläum: 99 Jahre Element 75.

van Gerven, David; Wickleder, Mathias S.

The couple Ida and Walter Noddack discovered the element rhenium in 1925 and obtained substantial amounts of it by processing over 600 kilograms of the mineral molybdenite. They published a paper on the production of one gram of rhenium and proposed the name rhenium for the element. They received support from the Emergency Association of German Science and the company Siemens & Halske. Nowadays, rhenium is mainly extracted from processing sulfidic molybdenum ores. It is primarily used in the production of alloys, especially in turbine blades of jet engines, and also finds application in heterogeneous catalysts. Rhenium has a complex chemistry and differs significantly from its group homologue manganese. It is often used as a surrogate for the radioactive element technetium, although the two metals differ in their chemical behavior. Further investigations into the chemical behavior of rhenium and technetium are necessary.
