What does rhenium mean in English?
Definition of rhenium : a rare heavy metallic element that is obtained either as a gray powder or as a silver-white hard metal, is usually extracted as a by-product of molybdenum smelting, and is used especially in catalysts and alloys — see Chemical Elements Table.

What is the symbol of nickel?
NiNickel / Symbolnickel (Ni), chemical element, ferromagnetic metal of Group 10 (VIIIb) of the periodic table, markedly resistant to oxidation and corrosion.
What is BH in chemistry?
bohrium (Bh), a synthetic element in Group VIIb of the periodic table. It is thought to be chemically similar to the rare metal rhenium.
How much rhenium is in the world?
about 1 part per billionRhenium is one of the rarest and most dispersed metallic elements in Earth's crust, with abundance estimated to be about 1 part per billion.Jun 13, 2018
What element has a symbol of RN?
radonradon (Rn), chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium. (Radon was originally called radium emanation.)
Why is rhenium important?
Rhenium is very hard, it resists corrosion but slowly tarnishes in moist air. Rhenium is used as an important component in superalloys for blades in turbine engines and this is the major use today. Rhenium is an ideal metal for use at very high temperatures, which makes it suitable for rockets motors.
How strong is rhenium?
With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust. Rhenium has the third-highest melting point and highest boiling point of any stable element at 5869 K.
What is the symbol of rhenium?
ReRhenium / Symbol
Where does rhenium come from?
Rhenium is essentially a by-product of a by-product, extracted from molybdenum, which is itself a by-product of mining porphyry copper deposits. Nobody actually mines rhenium. Rhenium is usually extracted from the flue gases and dust produced in roasting molybdenum concentrates. (In Kazakhstan, however, it also exists in sedimentary copper deposits.)
Will rhenium demand weaken?
Demand for rhenium looks unlikely to weaken for some time, especially in these times both of high fuel prices and environmental concern. And any new uses for the metal will only strengthen this demand further.
Is rhenium available on the LME?
Rhenium, like moly, is available neither on the LME nor on any other exchange. And, most probably, never will be. If, however, an investor wants to invest in the physical metal, it is available either from the likes of BASF, Rhenium Alloys, Inc., H. Cross Company, etc., or, possibly, from a minor metals trading house that deals in rhenium.
Is rhenium a son of moly?
Rhenium is the "Son of Moly" for a couple of reasons. Not only is most rhenium today produced as a by-product of the copper and molybdenum mining industries, but like molybdenum, rhenium has some very special, if not unique, properties.
Rhenium has a very high boiling point and a very high melting point as well
Of all the elements in the world, rhenium has the highest boiling point of all. Think about that for a second. This makes things that contain rhenium very resistant to heat. In addition to having a high boiling point, rhenium also has one of the highest melting points, too.
Rhenium is stronger and more stable than many other elements
The strength and stability that you’ll get when you add rhenium to an application is unlike anything you’ve ever seen before. Products containing rhenium will keep on ticking no matter how hot that it might get. The rhenium will also prevent these products from warping over time.
Rhenium plays a key role in some very important applications
There are a bunch of things that contain rhenium in them these days. But rhenium is most commonly associated with jet engines. Rhenium is combined with nickel to manufacture jet engines that are capable of heating up to unthinkable temperatures.
var Kommer Namnet Rhenium ifrån?
- The ores from which rhenium was first isolated commercially come from the Rhine area; thus, the element’s name (humble) derives from the Latin term for the river Rhenus. BIRTHPLACE The Rhine was first isolated commercially from minerals found near the Rhine.
När upptäcktes Rhenium?
- Reindeer is very hard, corrosion resistant, but slowly stains in moist air. Rhenium is used as a key ingredient in superalloys for turbine engine blades and this is the main use today. Rhenium is an ideal metal to use at very high temperatures, making it suitable for rocket engines.
Vad är Ett Intressant Faktum Om Rhenium?
- Renius is only one of three elements that have a stable isotope that is less abundant than its radioisotope. The radioactive isotope of rhenium has a half-life of about 100,000,000,000 years. Reindeer has the highest boiling point of any element. Reindeer has the third highest melting point of all the elements.
Vad är Symbolen för Volfram?
- Bohri är ett kemiskt grundämne med symbolen Bh och atomnummer 107. Klassad som en övergångsmetall är bohri ett fast ämne vid rumstemperatur.
Hur bildades Rhenium?
- The rhinoceros was discovered in 1925 by German chemists Ida Tacke-Noddack, Walter Noddack, and Otto Carl Berg. In 1928, Noddack and Berg were able to extract 1 gram of rhenium from 660 kilograms of molybdenite. Today, reindeer is obtained as a by-product in molybdenum and copper refining.
Hur Stark är Rhenium?
- With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth’s crust. Renius has the third highest melting point at 5869 K and the highest boiling point of all stable elements.

The Soviet hammer, sickle and star are on a background reflecting the item’s use in lasers. A silvery white metal. Samarium-cobalt magnets are much stronger than iron magnets.
Hur Mycket Rhenium Finns Det I världen?
- Rhenium är ett av de sällsynta och mest förekommande metalliska grundämnena i jordskorpan, med ett uppskattat överflöd på cirka 1 del per miljard.
Hur är Rhenium?
- Rhenium är en sällsynt, silvervit, glänsande, tät metall. Korrosions- och oxidationsbeständig, men sker långsamt i fuktig luft. Av grundämnena har bara kol och volfram högre smältpunkter, och endast iridium, osmium och platina är tätare.
