The chemistry and scope of europium and europium compounds is reviewed here. We manufacture all these compounds and in most instances with these rare earth products , it is important to know the method of manufacture, solubilities, assays and trace impurities.
Rare earth compounds were named not because
the individual rare earth elements are rare but because each
individual rare earth element rarely exists as a single element
but a s a mixture of rare earth elements.
Europium
was discovered by Eugène-Antole Demarçay, a French chemist, in
1896. Demarçay suspected that samples of a recently discovered
element samarium, were contaminated with an unknown element. He
was able to produce reasonably pure europium in 1901. Today,
europium is primarily obtained through an ion exchange process
from monazite sand ((Ce, La, Th, Nd, Y)PO4),
a material rich in rare earth elements. The composition of
monozite ore is the basis for rare earth impurities found in
europium compounds and the level of impurities is directly
related to the separation and source of these ores.

Europium chloride, bromide and nitrates are isolated as the hexahydrates and are very soluble in water. Anhydrous halides are also available. Europium acetate is somewhat soluble in water. (It is important to work with the manufacturer of your rare earth products because in the case of acetates the solubility varies widely depending on the method of manufacture and reaction conditions.
A new exciting europium compound is europium trifluoroacetate which is very soluble in water and has new uses as a catalyst in organic synthesis. Europium oxalate, carbonate and sulfate are insoluble in water and exist as a defined hydrate. These compounds can also be dehydrated.
Another example of purchasing rare earth compounds from a known manufacturer is europium fluoride. The rare earth fluorides are used in advanced material films, lens and glasses. In virtually all applications the fluoride should be carbonate free. Rare Earth Products, Inc. uses a proprietary process to make carbonate free rare earth fluorides.
Rare earth Products, Inc makes the most extensive list of rare earth metal beta diketonates. These organometallic compounds are used for MOCVD, spin coating, catalysts and NMR shift reagents to name a few advanced applications. The compounds offered include rare earth metal complexes with
acetylacetonate or 2,4-pentanedionate ACAC
hepatfluorodimethyloctanedionate FOD
hexafluoroacetyacetonate HFAC
tetrametylheptanedionate TMHD
trifluroacetylacetonate TFAC
chiral ligands OPT etc.
Most of these compounds are used because of the physical vapor pressure, volatility and organic solvent solubility. Contact our technical service department to get physical data such as melting points, sublimation temperatures, solubility, boiling points, etc - techservice@rareearthproducts.com.
Rare Earth Products, Inc also manufactures the organic soluble compounds europium 2-ethylhexanoate and europium cyclohexanebutyrate. These metal organic compounds are soluble in organic solvents. We can also custom synthesize various rare earth compounds by adding various ligands, dehydrating and coordinating various organic solvents to enhance non polar solubility. Contact techservice@rareearthproducts.com.
The intermetallics europium sulfide, europium selenide and europium telluride are available upon request. Europium trifluoromethanesulfonate or europium triflate is available and useful as a Friedel -Crafts catalyst as the anhydrous salt or the hydrate. A new compound europium thenoyltrifluoroacetonate is used as a thermal laser dye
