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.
Rhodium is a hard, silvery, durable metal that has a high reflectance. Rhodium metal does not normally form an oxide, even when heated. [25] Oxygen is absorbed from the atmosphere only at the melting point of rhodium, but is released on solidification. [26] Rhodium has both a higher melting point and lower density than platinum.
Over time, however, the price of the metal has dropped. ... Rhodium daily price 1992-2022 Price of gold 1915-2022 Palladium prices 1977-2022.
Rhodium daily price 1992–2022. Rhodium is used widely in automotive catalytic converters. Many countries have agreed to the Paris climate accord to cut car emissions and have higher standards for exhaust. South Africa produces 80–90% of Rhodium each year. Russia is the second largest producer of rhodium but it is around 1%.
If the rhodium metal was then left for 20 years after fission, the 13.3 grams of rhodium metal would contain 1.3 kBq of 102 Rh and 500 kBq of 102m Rh. Rhodium has the highest price of these precious metals ($440,000/kg in 2022 [ 3 ] ), but the cost of the separation of the rhodium from the other metals needs to be considered [ editorializing ...
Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number; [5] siderophiles shown in yellow Graphs of abundance against atomic number can reveal patterns relating abundance to stellar nucleosynthesis and geochemistry.
Sibanye-Stillwater has established itself as one of the world's largest primary producers of platinum, palladium, and rhodium and is also a top-tier gold producer. It produces other platinum group metals (PGMs) such as iridium and ruthenium, along with chrome, copper and nickel as by-products. The Group has recently begun to build and diversify ...
