inorganic In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as ''inorganic chemist ...

chemical compound A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element ...

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 Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. The Mohs sca ...

contains admixtures of yttrium.

Synthesis

YF₃ can be produced by reacting fluorine with

yttria Yttrium oxide, also known as yttria, is Y2 O3. It is an air-stable, white solid substance. The thermal conductivity of yttrium oxide is 27 W/(m·K). Uses Phosphors Yttria is widely used to make Eu:YVO4 and Eu:Y2O3 phosphors that give the red ...

or yttrium hydroxide with hydrofluoric acid. :Y(OH)₃ + 3HF → YF₃ + 3H₂O

Occurrence and uses

It occurs as the mineral waimirite-(Y). Yttrium(III) fluoride can be used for the production of metallic yttrium, thin films, glasses and ceramics.
