B4 Sr2 Ir4
semiconductor· B4 Sr2 Ir4
B₄Sr₂Ir₄ is an ternary intermetallic compound combining boron, strontium, and iridium—a research-phase material belonging to the family of transition metal borides and rare-earth intermetallics. This compound is primarily of interest in fundamental condensed-matter physics and materials research rather than established commercial applications, with potential relevance to high-temperature structural materials, thermoelectric systems, or exotic electronic applications where iridium's high electronegativity and boron's covalent network-forming character create unusual bonding and transport properties.
