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.
Scandium-stabilized zirconia enjoys a growing market demand for use as a high-efficiency electrolyte in solid oxide fuel cells. [citation needed] The USGS reports that, from 2015 to 2019 in the US, the price of small quantities of scandium ingot has been $107 to $134 per gram, and that of scandium oxide $4 to $5 per gram.

The price of dysprosium oxide was US$994/kg in 2011, but dropped to US$265/kg by 2014. [ 64 ] On August 29, 2014, the WTO ruled that China had broken free-trade agreements, and the WTO said in the summary of key findings that "the overall effect of the foreign and domestic restrictions is to encourage domestic extraction and secure preferential ...
Aluminium–scandium alloys (AlSc) are aluminum alloys that consist largely of aluminium (Al) and traces of scandium (Sc) as the main alloying elements.In principle, aluminium alloys strengthened with additions of scandium are very similar to traditional nickel-base superalloys in that both are strengthened by coherent, coarsening resistant precipitates with an ordered L1 2 structure.
In all four halides, the scandium is 6-coordinated. They can be prepared by reacting scandium oxide or scandium hydroxide with the corresponding acid: [3] Sc(OH) 3 + 3 HX → ScX 3 + 3 H 2 O. The halides are Lewis acids; for example, ScF 3 dissolves in a solution containing excess fluoride ion to form [ScF 6] 3−. The coordination number 6 is ...

American drivers had it rough back in 1981. The average price of gasoline spiked to $1.353 a gallon that year -- up from $1.221 in 1980 and more than double the price just three years earlier....
Per Theodor Cleve demonstrated the equivalence of Nilson's scandium and Mendeleev's hypothetical ekaboron. [9] Nilson and Sven Otto Pettersson were the first to isolate titanium metal in a relatively pure form, extracting a 95% pure sample in 1887. Jöns Jacob Berzelius had extracted titanium metal in 1825, but only in a very impure form. [1]
