· JVASP-61654· ScB2Ir3

ScB2Ir3 is an intermetallic ceramic compound combining scandium, boron, and iridium—a ternary system within the high-entropy ceramic family. This material is primarily of research interest rather than established commercial production, studied for its potential in extreme-environment applications where high melting point, oxidation resistance, and hardness are critical. The iridium content makes it exceptionally dense and costly, positioning it as a candidate for specialized aerospace and high-temperature structural applications if manufacturing and cost barriers can be overcome.
