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. SynthesisYF3 can be produced by reacting fluorine with yttria or yttrium hydroxide with hydrofluoric acid. Y(OH)3 + 3HF → YF3 + 3H2O Occurrence and usesIt occurs as the mineral waimirite-(Y).[1] Yttrium(III) fluoride can be used for the production of metallic yttrium, thin films, glasses and ceramics. HazardsConditions/substances to avoid are: acids, active metals and moisture.
