Ytterbium(III) fluoride (YbF
₃) is aninorganicchemical compound that is insoluble in water. Like other Ytterbium compounds, it is a rather unremarkable white substance.^[3] Ytterbium fluoride has found a niche usage as a radio-opaque agent in the dental industry to aid in the identification of fillings under X-ray examination.^[4]
