The element Rhenium is number 75 on the periodic table and is grouped as a refractory metal. Rhenium is a rare, silvery-white, dense element that resists corrosion and oxidation, but will eventually tarnish in an environment that contains moisture.
Of all the elements only two, carbon and tungsten, surpass Rhenium with the highest melting point. Rhenium is also among the elements with the highest density, does not have a ductile to brittle transition temperature and does not form carbides. Despite its density, Rhenium is ductile and malleable.
High resistivity, combined with low vapor pressure, Rhenium is an ideal material for filament applications. Rhenium exhibits excellent resistance to corrosion, resists acid attack and the mechanical effects of electrical erosion. Rhenium has a beneficial effect as an alloying additive with other refractory metals as it greatly enhances the ductility and tensile strength of these alloys.
Rhenium does not occur freely in nature nor does it exist as a compound, but it is widely spread throughout the Earth’s crust. Commercial production of Rhenium is obtained as the byproduct of refining and extraction from the flue dusts of copper and molybdenum smelters.
