The chemistry and scope of scandium  and scandium 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. Dmitri Mendeleev predicted the existence of an element that he called ekaboron, with an atomic mass between 40 and 48 in 1869. Ten years later Lars Fredrik Nilson found a new element in the minerals euxenite and gadolinite from Scandinavia. He was able to prepare 2 gram of scandium oxide of high purity. He named it scandium, from the Latin Scandia meaning "Scandinavia". Nilson was apparently unaware of Mendeleev's prediction, but Per Teodor Cleve recognized the correspondence and notified Mendeleev. 

Scandium is distributed sparsely and occurs in trace amounts in many minerals. Rare minerals from Scandinavia and Madagascar such as thortveitite, euxenite, and gadolinite are the only known concentrated sources of this element. Thortveitite can contain up to 45%, as scandium(III) oxide.

Scandium is more common in the sun and certain stars than on Earth. Scandium is only the 50th most common element on earth (35th most abundant in the Earth's crust), but it is the 23rd most common element in the sun.

Scandium chloride, bromide and nitrates are isolated as the hexahydrates and are very soluble in water. Anhydrous halides are also available. Scandium 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 scandium compound is scandium trifluoroacetate which is very soluble in water and has new uses as a catalyst in organic synthesis. Scandium 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 scandium 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 scandium 2-ethylhexanoate and scandium cyclohexanebutyrate. These metal organic  compounds are soluble in organic solvents. We can also custom synthesize various rare earth p compounds by adding various ligands, dehydrating and coordinating various organic solvents to enhance non polar solubility. Contact techservice@rareearthproducts.com.

The intermetallics scandium sulfide, scandium selenide and scandium telluride are available upon request. Scandium trifluoromethanesulfonate or scandium triflate is available and useful as a Friedel -Crafts catalyst as the anhydrous salt or the hydrate. A new compound scandium thenoyltrifluoroacetonate is used as a thermal laser dye.
