Used as a catalyst in organic synthesis and in the petroleum industry for cracking hydrocarbons.

Employed in the production of specialized glasses and ceramics that require high refractive index and thermal stability. Plays a role in solid-state lasers and infrared absorbing glass.

Utilized in electronic components and in the development of samarium-cobalt magnets, which are strong permanent magnets used in high-performance motors and sensors.

Applied in nuclear reactors as a neutron absorber due to its high neutron capture cross-section.

Used in phosphors for certain display screens and radiation detection devices, such as neutron sensors.

Employed in energy research, including materials for solid oxide fuel cells (SOFC) to enhance electrolyte electrical conductivity.
