Rhenium: use

Usually rhenium is not used in its elemental form but as a blending compoment in many different alloys. Abt. 70% of the rhenium is used as an additive in nickel superalloys. These alloys are required for the production of turbine blades in aircraft engines. An addition of 4 to 6% of rhenium improves the creep- and fatigue behaviour at high temperatures. A further important range is the product APR, ammonium perrhenate. APR is used as a catalyst in the petrochemical industry but also in shale gas- and oil production.

 

Rhenium: history and occurrence

Rhenium was discovered by Walter Noddack, Ida Tacke and Otto Berg in 1925 in a columbite when they were looking for the elements eka- and dwi-manganese. As the samples contained only small quantities of these elements they had to be enriched by separating the other components. Eventually the later rhenium could be detected by x-ray spectroscopy. Noddack and Tacke claimed also to have found very small quantities of Eka-manganese (later technetium) but they were not able to isolate the element. They named the elements after their home regions, i.e rhenium after Rhenus (latin term for Rhine) and masurium after Masuria in Poland. However, these names no longer played a role after thechnetium was discovered in 1937. In 1928 Noddack and Tacke managed for the first time to extract one gram of rhenium from 660 kg molybdenum ore. Due to the hight costs the production of significant quantities started only in 1950 when there was a higher demand for newly developed tungsten rhenium- and molybdenum rhenium alloys. In 2013 the world’s annual production of rhenium was about 50.000 kg.
