Yttrium(III) fluoride is an inorganic chemical compound with the chemical formula YF3. It is not known naturally in 'pure' form. The fluoride minerals containing essential yttrium include tveitite-(Y) (Y,Na)6Ca6Ca6F42 and gagarinite-(Y) NaCaY(F,Cl)6. Sometimes mineral fluorite contains admixtures of yttrium.
- Y(OH)3 + 3HF → YF3 + 3H2O
Occurrence and uses
Yttrium(III) fluoride can be used for the production of metallic yttrium, thin films, glasses and ceramics.
