· Sm2 B4 Ru4

Sm₂B₄Ru₄ is a ternary intermetallic compound containing samarium, boron, and ruthenium, belonging to the rare-earth boride family of advanced ceramics and semiconductors. This is primarily a research material studied for its potential electronic and thermal properties; it has not seen widespread industrial adoption. The material family is of interest for high-temperature applications and advanced device physics where rare-earth intermetallics offer tunable band structures and potential superconducting or strongly correlated electron behavior.
