Yttrium(III) fluoride
Yttrium 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- 6Ca6Ca6F42 and gagarinite- NaCaY6. Sometimes mineral fluorite contains admixtures of yttrium.Synthesis
YF3 can be produced by reacting fluorine with yttria or yttrium hydroxide with hydrofluoric acid.Occurrence and uses
It occurs as the mineral waimirite-.
Yttrium fluoride can be used for the production of metallic yttrium, thin films, glasses and ceramics.Hazards
