The chemistry and scope of dysprosium  and dysprosium 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 as a mixture of rare earth elements. French chemist Paul Émile Lecoq de Boisbaudran, while working with holmium oxide, separated dysprosium oxide from it in Paris in 1886. His procedure for isolating the dysprosium involved dissolving dysprosium oxide in acid, then adding ammonia to precipitate the hydroxide. He was only able to isolate dysprosium from its oxide after more than 30 attempts at his procedure. Upon succeeding, he named the element dysprosium from the Greek dysprositos (δυσπρόσιτος), meaning "hard to get". However, the element was not isolated in relatively pure form until after the development of ion exchange techniques by Frank Spedding at Iowa State University in the early 1950s.

The composition of monozite ore is the basis for rare earth impurities found in dysprosium compounds and the level of impurities is directly related to the separation and source of these ores. Dysprosium is never encountered as a free element, but is found in many minerals, including xenotime, fergusonite, gadolinite, euxenite, polycrase, blomstrandine, monazite and bastnasite; often with dysprosium and holmium or other rare earth elements. Currently, most dysprosium is being obtained from the ion-adsorption clay ores of southern China. In the high yttrium version of these, dysprosium happens to be the most abundant of the heavy lanthanides, comprising up to 7–8% of the concentrate (as compared to about 65% for yttrium).

Level of impurities:

 99.9%(REO)  1000ppm total rare earth oxide impurities

99.99%(REO)  100ppm total rare earth oxide impurities

99.999%(REO)  10ppm total rare earth oxide impurities

99.9999%(REO)  1ppm total rare earth oxide impurities

Dysprosium chloride, bromide and nitrates are isolated as the hexahydrates and are very soluble in water. Anhydrous halides are also available. Dysprosium 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 dysprosium compound is dysprosium trifluoroacetate which is very soluble in water and has new uses as a catalyst in organic synthesis. Dysprosium 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 dysprosium 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

hexafluoracetylacetonate 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 dysprosium 2-ethylhexanoate and dysprosium 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 dysprosium sulfide, dysprosium selenide and dysprosium telluride are available upon request. Dysprosium trifluoromethanesulfonate or dysprosium triflate is available and useful as a Friedel -Crafts catalyst as the anhydrous salt or the hydrate. A new compound dysprosium thenoyltrifluoroacetonate is used as a thermal laser dye.
