Used in research and development of advanced magnetic materials due to its strong paramagnetic properties. Plays a role in the synthesis of dysprosium-containing compounds for use in high-strength permanent magnets, especially in applications requiring performance at elevated temperatures, such as electric vehicle motors and wind turbine generators. Also utilized in doping scintillation detectors for neutron detection in nuclear applications. Its hydrated sulfate form is often preferred in solution-based chemical processes and laboratory studies involving rare earth sulfates.
