Dysprosium(III) fluoride is an inorganic compound of dysprosium with a chemical formula DyF3.
Dysprosium(III) fluoride can be produced by mixing dysprosium(III) chloride or dysprosium(III) carbonate into 40% hydrofluoric acid. [1]
DyF3 can also be produced by hydrothermal reaction of dysprosium nitrate and sodium tetrafluoroborate at 200 °C. [2]
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: [3]
Dysprosium(III) fluoride is a white, odorless solid that is insoluble in water. [4] It has an orthorhombic crystal structure with the space group Pnma ( space group no. 62). [5]
