· JVASP-37330· TbB4Ir4

TbB4Ir4 is a ternary ceramic compound combining terbium, boron, and iridium—a research-phase material in the family of refractory boride ceramics. This compound represents an experimental exploration of high-density ceramic systems that leverage iridium's exceptional thermal and chemical stability alongside boron's refractory properties, though industrial deployment remains limited. The material is of primary interest to materials researchers investigating advanced ceramics for extreme-environment applications where conventional refractories or superalloys fall short.
