Dysprosium(III) fluoride


Dysprosium fluoride is an inorganic compound of dysprosium with a chemical formula DyF3.

Production

Dysprosium fluoride can be produced by mixing dysprosium chloride or dysprosium carbonate into 40% hydrofluoric acid.
DyF3 can also be produced by hydrothermal reaction of dysprosium nitrate and sodium tetrafluoroborate at 200 °C.
DyF3 can also be produced when dysprosium oxide and ammonium bifluoride are mixed and heated to 300 °C until the oxide is porous, and continued to heat to 700 °C. When hydrogen fluoride is introduced, a reaction occurs:

Properties

Dysprosium fluoride is a white, odorless solid that is insoluble in water. It has an orthorhombic crystal structure with the space group Pnma.
