Rhenium is a dense, metallic element with the chemical symbol Re. Rhenium is very rare, has an extremely high melting point and boiling point. It is primarily used as a catalyst to refine petroleum, and as a superalloy to construct aircraft turbine blades. Rhenium may occur within the mineral molybdenite ((Mo,Re)S 2) or rarely as rheniite (ReS ...

Ruthenium, Ru. Ruthenium (Ru) is a rare transition metal that belongs to the platinum group of the periodic table. Exhibiting a shiny, silvery appearance, ruthenium is known for its impressive hardness and resistance to corrosion, even at high temperatures. In the electronics industry, ruthenium is utilized as a crucial component for some types ...

Other elements are sometimes considered to be precious metals. Rhenium is commonly included on the list. Some sources consider indium to be a precious metal. Alloys made using precious metals are themselves precious. A good example is electrum, a naturally occurring alloy of silver and gold.

Rhenium–osmium method. The decay scheme in which rhenium-187 is transformed to osmium-187 shows promise as a means of studying mantle–crust evolution and the evolution of ore deposits. Osmium is strongly concentrated in the mantle and extremely depleted in the crust, so that crustal osmium must have exceedingly high radiogenic-to …

E-beam Evaporation of Ruthenium (Ru) Ruthenium is difficult to deposit by e-beam evaporation, but not impossible. Ruthenium has a vapor pressure of 10-4 Torr at 2,260°C and is rated as 'poor' for e-beam evaporation due to the high temperatures required to achieve a decent deposition rate. We have not yet qualified a crucible liner material for e …

A basic analysis of a Mo roaster producing Re was given by Nuss and Eckelman (2014), which uses value to ascribe impacts based on 86.5% to Mo and 13.5% to Re and gives 450 kg CO 2 -eq/kg Re. At global production of 59 t Re in 2021, this would mean Re is responsible for ∼26.5 kt CO 2 -eq of greenhouse gas pollution.

Uses. Rhenium is used as an additive to tungsten- and molybdenum-based alloys to give useful properties. These alloys are used for oven filaments and x-ray machines. It is also used as an electrical contact material as it resists wear and withstands arc corrosion.
