Dysprosium(III) fluoride is a colorless hexagonal or rhombic crystal that is insoluble in water and dilute acid and emits hydrogen fluoride by co heating with concentrated sulfuric acid. Add hydrofluoric acid to Dysprosium(III) chloride solution to precipitate crystals.

The application of Dysprosium(III) fluoride is mainly used to prepare dysprosium containing metal alloys. Its application examples are as follows: 1) Prepare rare earth dysprosium alloys by adding the mixture of rare earth oxide and Dysprosium(III) oxide as electrolytic raw materials in the fluoride molten salt system for electrolytic production. 2) A coated Nd-Fe-B sintered magnet is prepared. On the Nd-Fe-B sintered magnet, a transition layer containing dysprosium or terbium is formed inside the magnet in contact with the Dysprosium(III) fluoride or terbium fluoride coating. 3) Prepare a dysprosium metal alloy, calculated by weight percentage, consisting of 10% to 50% dysprosium and 50% to 90% neodymium or 50% to 90% neodymium and 0% to 30% praseodymium.

The prepared FeF3 and H2SiF6 are both soluble in acidic solutions, while KSP (AlF3)=2.015 × 10-5, the generated AlF3 has a low solubility in solution and is insoluble in acidic solutions. Most of it will co precipitate in DyF3. The aluminum in the solution will co precipitate in DyF3. Therefore, in order to reduce the entry of aluminum into rare earth fluoride, it is necessary to remove aluminum as much as possible before fluorination, and to reduce subsequent washing workload, it is also necessary to remove iron, chemical, and silicon impurities from the solution as much as possible. The conventional hydrogen fluoride precipitation method can reduce costs for rare earth separation plants, but due to the difficulty in washing and clarifying after fluoride precipitation, it is not conducive to removing non rare earth impurities. In order to stably produce high-quality Dysprosium(III) fluoride, the process first treats the non rare earth impurities in Dysprosium(III) chloride solution, and then uses a composite fluoride agent to prepare coarse grained Dysprosium(III) fluoride precipitates in Dysprosium(III) chloride solution. Dysprosium(III) fluoride precipitates are washed, filtered, dried, and then vacuum dehydrated to produce high-quality Dysprosium(III) fluoride products.
