Ba4 P4 Ir4

Ba₄P₄Ir₄ is an experimental intermetallic compound containing barium, phosphorus, and iridium, representing a quaternary phase that bridges rare-earth-free alternatives to conventional semiconductors and functional materials. This material remains primarily in research and development stages, with potential applications in solid-state electronics, catalysis, or high-temperature semiconductor applications where the combination of transition metal (iridium) and main-group elements (barium, phosphorus) may offer unique electronic or structural properties. Research into such phosphide-based intermetallics is driven by the need for novel semiconductors with tunable band gaps and improved thermal stability compared to conventional III–V or II–VI compounds.
