Description and Uses

Yttrium(III) chloride is an inorganic compound of yttrium and chloride. It exists in two forms, the hydrate (YCl3(H2O)6) and an anhydrous form (YCl3). Both are colourless solids that are highly soluble in water and deliquescent.
Yttrium(III) chloride is used as a precursor for titanium-containing ceramics. It is used as an analytical reagent, as a catalyst and in superconductors. It is also used in the production of yttrium alkyl alkoxide complexes.

Yttrium chloride (YCl3) decomposes at the relatively low temperature of 100°C. This makes it useful as a reagent in chemical laboratories.
