Yttrium(III) fluoride is an inorganic chemical compound with the chemical formula YF3. It is not known naturally in 'pure' form. Its CAS. is 13709-49-4. MW is 145.90. It occurs as a white powder.
Yttrium(III) fluoride can be used for the production of metallic yttrium, thin films, glasses and ceramics. Yttrium Fluoride is a water insoluble Yttrium source for use in oxygen-sensitive applications, such as metal production. In extremely low concentrations (ppm), fluoride compounds are used in health applications.
Fluoride compounds also have significant uses in synthetic organic chemistry. They are commonly also used to alloy metal and for optical deposition. Certain fluoride compounds can be produced at nanoscale and in ultra high purity forms. Yttrium has the highest thermo-dynamic affinity for oxygen, useful in ceramics for crucibles for molten reactive metals, in florescent phosphors, computer displays and automotive fuel sensors. Yttria stabilized zirconia is used in high temperature applications and as an electrolyte in fuel cells. Yttrium Fluoride is generally immediately available in most volumes.
