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]
