Rhenium - Wikipedia

Rhenium is a chemical element with the symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table.With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust.Rhenium has the third-highest melting point and second-highest boiling point of any stable element at 5903 K

Rhenium - an overview | ScienceDirect Topics

Nevertheless, in anoxic systems such as the Black Sea, rhenium does show substantial decreases in concentration (nonconservative behavior) that have been attributed to removal at the surface of anoxic sediments. However, in the modern ocean these anoxic systems are too rare to substantially alter the distributions of rhenium in the water column.

Rhenium in Molybdenite: a Database Approach to

Molybdenite is the worlds principal source of rhenium (Re), a critical element in multiple high-tech applications. However, the Re contents in molybdenite vary by orders of magnitude on scales ranging from single grains to whole deposits. In order to better understand the systematics of this variation and what geochemical factors control molybdenite Re concentration, and hence overall Re

A contribution to the chemistry of rhenium

reductor, indicates that rhenium forms a compound in which it has a valency of minus one, and that the rhenium in this compound is oxidized to a valency of plus one if the diluted sulphuric acid solution is protected from oxygen and warmed to approximately 50° C. In the course of the investigation, it was also found (1) that rhenium can be

Rhenium : A Critical Rare Metal for the Military Engines

Roughly 52,000 kilograms, or 52 metric tons, of rhenium was produced worldwide during 2017. The United States is by far the largest consumer of this critical mineral, accounting for 42,600 metric tons, or nearly 82 percent, of last years global production. Nearly 80 percent of the rhenium consumed in the United States is used in superalloys []
