Yttrium(III) chloride

Yttrium oxide or hydroxide is dissolved in hydrochloric acid, evaporated, concentrated, cooled, and then washed with ethanol and ether to obtain its hexahydrate. The hexahydrate is then dehydrated in a hydrogen chloride stream at 70°C to obtain its monohydrate. Finally, the monohydrate is heated in a helium stream at 1000°C to obtain anhydrous Yttrium(III) chloride.

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.

Reddish-white, transparent, deliquescent prisms. D 2.18, decomposes at 100C. Soluble in water and alcohol; insoluble in ether.

Yttrium(III) chloride, reacting with potassium alkoxotitanates, forms precursors 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.
