The price for a (metric) ton [1000 kg] of Lanthanum oxide 99% (FOB China in USD/Mt) is given by the Institute of Rare Earths Elements and Strategic Metals (IREESM) as below $2,000 for most of the period from early 2001 to September 2010 (at $10,000 in the short term in 2008); it rose steeply to $140,000 in mid-2011 and fell back just as rapidly ...
The traditional "rare-earth chloride", as a commodity chemical, was also used to extract the individual rare earths by companies that did not wish to process the ores directly. As of 2007, mischmetal is typically priced at less than 10 USD per kilogram, and the underlying rare-earth chloride mixtures are typically less than US$5/kg.
Lanthanum(III) oxide, also known as lanthana, chemical formula La 2 O 3, is an inorganic compound containing the rare earth element lanthanum and oxygen. It is used in some ferroelectric materials, as a component of optical materials, and is a feedstock for certain catalysts, among other uses.
The hydrogen storage density per unit volume (crystal) of LaNi 5 H 6.5 at 2 bar is equal to the density of gaseous molecular hydrogen at 1800 bar, and all hydrogen can be desorbed at 2 bar. Although the hydrogen storage density in practical applications is reduced due to the aggregation of some LaNi 5 powders, it is still higher than the ...
Lanthanum oxalate is an inorganic compound, a salt of lanthanum metal and oxalic acid with the chemical formula La 2 (C 2 O 4) 3. [1] [2] Synthesis.
Lanthanum(III) sulfide can be prepared from the effect of sulfur vapor on metallic lanthanum: 2 La + 3 S → La 2 S 3. It can also be prepared from the effect of hydrogen sulfide on lanthanum: 2 La + 3H 2 S → La 2 S 3 + 3 H 2. The effect of hydrogen sulfide on lanthanum oxide in the presence of reducing agents also produces lanthanum(III ...
