Used in the production of neodymium-iron-boron (NdFeB) permanent magnets to improve high-temperature performance and corrosion resistance. Employed in metal halide lamps to enhance light output and color quality, particularly for film and photography lighting. Applied in nuclear reactors as a neutron absorber due to its high thermal neutron capture cross-section. Utilized in dosimeters and radiation detection devices for monitoring neutron exposure. Also used in research and development of magnetic refrigeration systems operating near room temperature.
