Technical specifications

Renium is a refractory metal, close in properties to the refractory elements of the sixth group (molybdenum, tungsten). According to the melting point, rhenium is second only to tungsten, it occupies the fourth place after osmium, platinum and iridium in density.

Description Value
Atomic (molar) mass g / mol 186.2
Degrees of oxidation 7, 6, 5, 4, 3, 2, -1
Density [g / cm3] 21.02
Melting point t ° C 3186 ° С
Heat of melting kJ / mol 34
Thermal conductivity K [W / (m · K)] 48
Heat of evaporation kJ / mol 704

Production

Rhenium is extracted from raw materials with an extremely low percentage content — from copper sulphide, as well as molybdenum ores. Raw materials are processed by pyrometallurgical methods (melting, converting, oxidizing firing).

Using

In electrical engineering, electronics from rhenium alloys, mesh, filament, cathode heaters for cathode-ray tubes are made; in thermionic generators, generator and receiver-amplifying lamps — filaments of ionic manometers and mass spectrometers. To measure the highest temperatures (about 2500 ° C), thermocouples BP5, BP20 are used. Re + W alloys are ideal for the production of filament.
