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.
