In the form of anthracite, price per carbon contained, assuming 90% carbon content. In the form of boric acid, price per boron contained. In the same year, stockpiles of US government helium were sold on auctions for average price of US$0.00989/L. Ĭrude helium sold to non-government users in United States in 2018. In 2016 Iran sold 32 tons of heavy water to United States for 1336 USD per kg deuterium. Also sold by same supplier in the form of heavy water at price of 3940 USD per kg deuterium. Does not include cost of storage and distribution.ĩ9.8% pure compressed deuterium gas, in lot size of 850 L (142 g).

Prices of hydrogen produced by distributed steam methane reforming, as predicted by H2A Production Model from United States Department of Energy, assuming price of natural gas of US$3/ MMBtu (US$10/MWh US$0.10/m 3). The price listing for radioisotopes is not exhaustive.Ībundance and total mass in Earth's crust ( mg / kg) For elements whose radiological properties are important, individual isotopes and isomers are listed. This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero. When there is no public data on the element in its pure form, price of a compound is used, per mass of element contained. Hydrogen, nitrogen, oxygen and chlorine are cheapest by volume at atmospheric pressure. However, both this and other routes of synthesis of precious metals via nuclear reactions is orders of magnitude removed from economic viability.Ĭhlorine, sulfur and carbon (as coal) are cheapest by mass. While the difficulty of obtaining macroscopic samples of synthetic elements in part explains their high value, there has been interest in converting base metals to gold ( Chrysopoeia) since ancient times, but only deeper understanding of nuclear physics has allowed the actual production of a tiny amount of gold from other elements for research purposes as demonstrated by Glenn Seaborg. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars. Carbon in the form of diamond can be more expensive than rhodium. Ir) whereas palladium and platinum both have several.

Of those elements, rhodium, caesium and gold have only one stable isotope ( 133

It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Data on elements' abundance in Earth's crust is added for comparison.Īs of 2020, the most expensive non- synthetic element by both mass and volume is rhodium. Listed here are mainly average market prices for bulk trade of commodities. This is a list of prices of chemical elements.
