GOLDMAN Sets $2,300 Price Target For Gold In 2021 20-11-20 FT : The new normal for gold 20-11-20 IG / ROSS NORMAN : Gold price outlook – where now after the pullback from ten-ye.. 20-11-20 Normally Re2O7 on alumina is used for this process.  Tungsten-rhenium wire was originally created in efforts to develop a wire that was more ductile after recrystallization. SAC preparation process.  Rhenium is probably not found free in nature (its possible natural occurrence is uncertain), but occurs in amounts up to 0.2% in the mineral molybdenite (which is primarily molybdenum disulfide), the major commercial source, although single molybdenite samples with up to 1.88% have been found. , Rhenium in the form of rhenium-platinum alloy is used as catalyst for catalytic reforming, which is a chemical process to convert petroleum refinery naphthas with low octane ratings into high-octane liquid products. , "Nipponium" redirects here. , Rhenium has a high melting point and a low vapor pressure similar to tantalum and tungsten. , Related by periodic trends, rhenium has a similar chemistry to that of technetium; work done to label rhenium onto target compounds can often be translated to technetium. November 22, 2020 Rhodium Price Today.  One application for the tungsten-rhenium alloys is X-ray sources. It can be prepared by many routes, a typical method is the reaction of Re2O7 and tetramethyltin: Analogous alkyl and aryl derivatives are known. The Engelhard Industrial Bullion (EIB) Price is indicative of the price at which BASF Corporation or BASF Metals Japan Limited, respectively, would be willing to sell the priced industrial grade metal to a hypothetical customer at a point in time and for delivery at a BASF facility. Terminal alkynes yield the corresponding acid or ester, internal alkynes yield diketones, and alkenes give epoxides.  Rhenium tungsten alloys are also applied as thermocouples to measure temperatures up to 2200 °C. (1963) "Ammonium Perrhenate" in, Hudson, A. , Rhenium diboride (ReB2) is a hard compound having the hardness similar to that of tungsten carbide, silicon carbide, titanium diboride or zirconium diboride. Do You Have Rhodium Bars to Sell? , Very little is known about the toxicity of rhenium and its compounds because they are used in very small amounts.  In 1928 they were able to extract 1 g of the element by processing 660 kg of molybdenite. Prices for the metal rose rapidly in early 2008, from $1000–$2000 per kg in 2003–2006 to over $10,000 in February 2008.  Chile has the world's largest rhenium reserves, part of the copper ore deposits, and was the leading producer as of 2005. MetalsDaily.com brings you all the latest gold news, live gold prices, price charts and precious metal events. These prices, however, declined during the global financial crisis that started during this time.  Kudriavy discharges up to 20–60 kg rhenium per year mostly in the form of rhenium disulfide. : Call 1-800-800-1865 to Lock Your Price!  Rhenium catalysts are very resistant to chemical poisoning from nitrogen, sulfur and phosphorus, and so are used in certain kinds of hydrogenation reactions.  The rising demand for military jet engines and the constant supply made it necessary to develop superalloys with a lower rhenium content.  Rhenium-molybdenum alloys are superconductive at 10 K; tungsten-rhenium alloys are also superconductive around 4–8 K, depending on the alloy. Element 113 was also discovered by a team of Japanese scientists and was named in respectful homage to Ogawa's work. It’s still relatively expensive because it is very rare.  Another major application is in platinum–rhenium catalysts, which are primarily used in making lead-free, high-octane gasoline. Rhenium has a hexagonal close-packed crystal structure, with lattice parameters a = 276.1 pm and c = 445.6 pm.  Recycling of used Pt-Re catalyst and special alloys allow the recovery of another 10 tons per year. Discovered in 1908, rhenium was the second-last stable element to be discovered (the last being hafnium). Salts of [Re2Cl8]2− feature a quadruple metal-metal bond. Rhenium is a chemical element with the symbol Re and atomic number 75. (2002) “Methyltrioxorhenium” in, "Atomic weights of the elements 2013 (IUPAC Technical Report)", "Corrected Values for Boiling Points and Enthalpies of Vaporization of Elements in Handbooks", "The High-Frequency Spectra of the Elements, Part II", "Names and symbols of the elements with atomic numbers 113, 115, 117 and 118 (IUPAC Recommendations 2016)", "The Properties of Superconducting Mo-Re Alloys", "The NUBASE2016 evaluation of nuclear properties", "Analysis: Super hot metal rhenium may reach "platinum prices, "Fourth generation nickel base single crystal superalloy", "Development of a Next-Generation Ni-base Single Crystal Superalloy", "Joint Development of a Fourth Generation Single Crystal Superalloy", "Design in an Era of Constrained Resources", "The Oxidation State of Rhenium and Its Role in Platinum-Rhenium", "The Tungsten-188 and Rhenium-188 Generator Information", "Personalized irradiation therapy for NMSC by rhenium-188 skin cancer therapy: a long-term retrospective study", https://en.wikipedia.org/w/index.php?title=Rhenium&oldid=988065301, Chemical elements predicted by Dmitri Mendeleev, Short description is different from Wikidata, Wikipedia indefinitely move-protected pages, Creative Commons Attribution-ShareAlike License, This page was last edited on 10 November 2020, at 20:57.
