Rhenium. Rhenium (Re) is a chemical element of the periodic table, located in the group 7 and the period 6, and has the atomic number 75. It is a rare, lustrous, silvery-white transition metal, whose name comes from the Latin word "Rhenus", which means the Rhine. It has the highest melting point and boiling point of all metals.

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.

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.
