· JVASP-154276· Tb5Ir3

Tb5Ir3 is an intermetallic ceramic compound combining terbium (a rare-earth element) with iridium, representing a high-density material system studied primarily in materials research rather than established industrial production. This compound belongs to the rare-earth intermetallic family, characterized by strong metallic bonding with ceramic-like brittleness, and is investigated for applications requiring extreme hardness, thermal stability, or specialized electronic properties at elevated temperatures. The terbium-iridium system is not widely commercialized but offers potential in niche high-performance sectors where rare-earth strengthening and iridium's corrosion resistance provide advantages over conventional ceramics or superalloys.
