Because of the low availability relative to demand, rhenium is expensive, with price reaching an all-time high in 2008–09 of US$10,600 per kilogram (US$4,800 per pound). As of 2018, its price had dropped to US$2,844 per kilogram (US$1,290 per pound) due to increased recycling and a drop in demand for rhenium catalysts. [12]
Refractory metals have high melting points, with tungsten and rhenium the highest of all elements, and the other's melting points only exceeded by osmium and iridium, and the sublimation of carbon. These high melting points define most of their applications. All the metals are body-centered cubic except rhenium which is hexagonal close-packed.
Kudriavy discharges up to 20–60 kg rhenium per year mostly in the form of rhenium disulfide. [100] [101] Named rheniite, this rare mineral commands high prices among collectors. [102] Ammonium perrhenate. Most of the rhenium extracted comes from porphyry molybdenum deposits. [103] These ores typically contain 0.001% to 0.2% rhenium. [6]
One of the largest bullion coins in the world was the 10,000-dollar Australian Gold Nugget coin minted in Australia, which consists of a full kilogram of 99.9% pure gold. In 2012, the Perth Mint produced a 1-tonne coin of 99.99% pure gold with a face value of $ 1 million AUD, making it the largest minted coin in the world with a gold value of ...
Bromopentacarbonylrhenium(I) is a precursor to other rhenium complexes. It reacts with zinc and acetic acid to give pentacarbonylhydridorhenium (HRe(CO) 5). [3]Re(CO) 5 Br + Zn + HO 2 CCH 3 → ReH(CO) 5 + ZnBrO 2 CCH 3
Rhenium(VI) oxide has an appearance similar to that of copper. Rhenium(IV) oxide (or rhenium dioxide) is an oxide of rhenium, with the formula ReO 2. This gray to black crystalline solid is a laboratory reagent that can be used as a catalyst. It adopts the rutile structure. It forms via comproportionation: [4] 2 Re 2 O 7 + 3 Re → 7 ReO 2
Rhenium diboride (ReB 2) is a synthetic high-hardness material that was first synthesized in 1962. [ 3 ] [ 4 ] The compound is formed from a mixture of rhenium , noted for its resistance to high pressure, and boron , which forms short, strong covalent bonds with rhenium.
