Used as a precursor in the production of rhenium metal, which is essential for manufacturing high-temperature superalloys in jet engines and gas turbines. Commonly employed in the synthesis of catalysts for petroleum reforming processes, helping to improve gasoline octane ratings. Applied in the electronics industry for making filaments and electrical contacts due to rhenium’s stability and conductivity. Also utilized in research and development of specialized coatings and in some medical isotope applications.
