· ScBIr3

ScBIr3 is an intermetallic ceramic compound combining scandium, boron, and iridium, belonging to the class of refractory intermetallics. This material is primarily of research and development interest rather than established commercial production, with potential applications in extreme-temperature structural applications where conventional ceramics or superalloys reach their performance limits. The combination of a light refractory element (scandium/boron) with a dense, high-melting-point transition metal (iridium) suggests engineering interest in high-stiffness, high-density systems for aerospace or chemical processing environments.
