Rhenium is a technology metal. Technology metals, but also rare earths, are well suited as an investment.

According to an EU study, rhenium has a value of 7.7 on an economic importance scale of 1-10. The raw material is significantly rarer than the most important precious metals, but not much more expensive in relation to them.

Fields of application

Aircraft turbines

Nickel superalloys

Platinum-rhenium catalysts

Thermocouples

Unleaded gasoline

Discovery

The element rhenium was first detected in 1925 by the German chemists Walter and Ida Noddack with the assistance of the X-ray specialist Otto Berg at the Physikalisch-Technische Reichsanstalt in Berlin. It was thus the last naturally occurring element to be discovered, isolated and inserted into Mendeleev's periodic table of elements. It was not until 1928, i.e. three years later, that the Noddack couple succeeded in extracting one gram of purest rhenium from 660 kilograms of molybdenum ore. Due to the high production costs, however, it did not become industrially significant until the 1950s. The element was named after Ida Noddack's home in the Lower Rhine region (Latin 'Rhenus' for Rhine).

Properties

Rhenium has a very high density of 21.03 g/cm3. This is exceeded only by the platinum group metals osmium (22.59 g/cm3), iridium (22.56 g/cm3) and platinum (21.45 g/cm3). Among the metals, it has an extremely high melting point of 3186°C, exceeded only by tungsten (3422°C). As an alloying component in so-called superalloys, rhenium prevents brittleness at low temperatures while improving fatigue behavior and strength at high temperatures.

Occurrence and extraction

With a frequency of only 0.0007 ppm in the earth's crust, rhenium is one of the rarest elements. Of the 80 stable elements, it ranks 78th. Only the noble gases krypton and xenon are rarer. In addition to its rarity, it does not occur in pure form, but is found exclusively bound in some ores and minerals. Since rhenium has similar properties to molybdenum, it is found primarily in molybdenum ores such as molybdenum disulfide MoS2. They can contain up to 0.2 percent rhenium. Molybdenum, in turn, is predominantly a byproduct of copper mining, so rhenium is consequently the byproduct of a byproduct. The largest copper deposits are located in Chile, Peru, China, the USA and the Congo. The technical extraction of rhenium takes place during the roasting of molybdenum ores. During this process, rhenium accumulates as an oxide in the resulting flue dust and can be bound with water containing ammonia. When hydrogen is added at high temperatures, the oxide reduces to elemental rhenium. According to the U.S. Geological Survey, 53.2 metric tons of rhenium were extracted worldwide in 2019, and 53.0 metric tons in 2020. By far the largest producer was Chile (57.7 percent), followed by Poland (15.7 percent) and the United States (14.7 percent).
