Yttrium(III) fluoride is an inorganic chemical compound with the chemical formula Y F₃. 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.^[1]^[2]

Synthesis

YF₃ can be produced by reacting fluorine with yttria or yttrium hydroxide with hydrofluoric acid.

Y(OH)₃ + 3HF → YF₃ + 3H₂O

Occurrence and uses

It occurs as the mineral waimirite-(Y).^[3]

Yttrium(III) fluoride can be used for the production of metallic yttrium, thin films, glasses and ceramics.

Hazards

Conditions/substances to avoid are: acids, active metals and moisture.
