Characteristic
Rhenium is a chemical element with the symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table.
Phase at STP：solid
Appearance：silvery-grayish
Melting point：3459 K (3186 °C, 5767 °F)
Boiling point：5903 K (5630 °C, 10,170 °F)
Density (near r.t.)：21.02 g/cm3
when liquid (at m.p.)：18.9 g/cm3
Heat of fusion：60.43 kJ/mol
Heat of vaporization：704 kJ/mol
Molar heat capacity：25.48 J/(mol·K)
Application
Rhenium is added to high-temperature superalloys that are used to make jet engine parts, using 70% of the worldwide rhenium production. Another major application is in platinum–rhenium catalysts, which are primarily used in making lead-free, high-octane gasoline.
