B57Ir43

B57Ir43 is an intermetallic ceramic compound containing boron and iridium in a 57:43 atomic ratio, representing a high-temperature ceramic material from the boron-iridium system. This material belongs to the family of refractory intermetallics and is primarily of research interest for extreme-temperature applications where thermal stability and hardness are critical; it is not widely commercialized in mainstream engineering. Engineers would consider B57Ir43 for specialized aerospace or high-temperature industrial contexts where conventional ceramics or metals prove insufficient, though material availability, processability, and cost typically limit its adoption to laboratory prototypes and specialized military or space applications.
