1. Introduction. Rhenium (Re), with a high melting point (3180 °C), high modulus and good ductility, has excellent high-temperature mechanical properties among refractory metals,, which makes it an ideal high-temperature structural material.An iridium coated rhenium (Ir/Re) combustion chamber has been successfully used in the 601HP satellite propulsion system, …

Rhenium-tungsten alloys including rhenium and from about 0.025% to less than about 10% by weight tungsten. The rhenium-tungsten alloys are formed by a process that includes coating rhenium metal powders with a liquid including a tungsten compound, drying the coated rhenium powder, compressing the dried coated powder to form a compact, and then sintering the …

All-electron density functional theory calculations were performed aiming to determine the equation of state and the dependence with pressure of the c / a ratio and the anisotropic compressibility for hexagonal-close-packed rhenium. Calculations were carried out up to maximum compression of 0.46, and the resulting total energy versus volume is well …

Rhenium - USGS

Rhenium is one of the rarest elements in Earth's continental crust; its estimated average crustal abundance is less than 1 part per billion. Rhenium is a metal that has an extremely high melting point and a heat-stable crystalline structure. More than 80 percent of the rhenium consumed in the world is used in high-temperature superalloys, especially those used to make turbine …

Rhenium was the lower one and indeed it was the last stable, non-radioactive, naturally-occurring element to be discovered. In 1905, Masataka Ogawa found it in the mineral thorianite from Sri Lanka. He realised from lines in its atomic spectrum that it contained an unknown element. He wrongly thought it was the one directly below manganese and ...

Rhenium in Wolframite. This is basically a fine powder which is said to have been determined by neutron activation analysis to be microscopic inclusions of rhenium in wolframite grains. No reason to doubt the claim. But it is a good bit of money to pay for a powder that, honestly, looks a lot like just about any other powder.

Rhenium is a greyish silver metal. Rhenium has remarkably high boiling point (5627 °C) and is categorized as the element with the highest boiling point. It also has one of the highest melting point (3170 °C ), second only to carbon and tungsten. Rhenium is a significantly dense metal (21.02 g/cm 3 ).

Rhenium was discovered by the German chemists Ida Tacke-Noddack, Walter Noddack and Otto Carl Berg in 1925. They detected rhenium spectroscopically in platinum ores and in the minerals columbite ((Fe, Mn, Mg)(Nb, Ta) 2 O 6), gadolinite ((Ce, La, Nd, Y) 2 FeBe 2 Si 2 O 10) and molybdenite (MoS 2).Rhenium is present in these materials only in trace amounts.

Rhenium is primarily used for high-temperature superalloys (used to manufacture turbine blades) and in platinum-rhenium catalysts to produce high-octane, lead-free gasoline. While rhenium is present in copper-molybdenum deposits in the United States, the United States has insufficient processing capacity to meet domestic need for rhenium.
