This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
In 1884, the pyramidal capstone of the Washington Monument was cast of 100 ounces of pure aluminium. By that time, aluminium was as expensive as silver. [18] The statue of Anteros atop the Shaftesbury Memorial Fountain (1885–1893) in London's Piccadilly Circus is also of cast aluminium. Over time, however, the price of the metal has dropped.
Since a typical used nuclear fuel contains about 3% fission products, one ton of used fuel will contain about 1.9 kg of ruthenium. The 103 Ru and 106 Ru will render the fission ruthenium very radioactive. If the fission occurs in an instant then the ruthenium thus formed will have an activity due to 103 Ru of 109 TBq g −1 and 106 Ru of 1.52 ...
Ruthenium dissolves in fused alkalis to give ruthenates (RuO 2− 4). It is not attacked by acids (even aqua regia) but is attacked by sodium hypochlorite at room temperature, and halogens at high temperatures. [11] Ruthenium is most readily attacked by oxidizing agents. [12] Small amounts of ruthenium can increase the hardness of platinum and ...
Ruthenium trichloride. The highest known ruthenium halide is the hexafluoride, a dark brown solid that melts at 54 °C.It hydrolyzes violently upon contact with water and easily disproportionates to form a mixture of lower ruthenium fluorides, releasing fluorine gas.
In finance, a spot contract, spot transaction, or simply spot, is a contract of buying or selling a commodity, security or currency for immediate settlement (payment and delivery) on the spot date, which is normally two business days after the trade date. The settlement price (or rate) is called spot price (or spot rate).
Pentamethylcyclopentadienyl ruthenium dichloride is an organoruthenium chemistry with the formula [(C 5 (CH 3) 5)RuCl 2] 2, commonly abbreviated [Cp*RuCl 2] 2. This brown paramagnetic solid is a reagent in organometallic chemistry. It is an unusual example of a compound that exists as isomers that differ in the intermetallic separation, a ...
(Benzene)ruthenium dichloride dimer is the organoruthenium compound with the formula [(C 6 H 6)RuCl 2] 2. This red-coloured, diamagnetic solid is a reagent in organometallic chemistry and homogeneous catalysis .
