Co4 Re4 B4
semiconductor· Co4 Re4 B4
Co₄Re₄B₄ is an experimental intermetallic boride compound combining cobalt, rhenium, and boron in a complex crystal structure. This material belongs to the family of high-entropy and multi-element borides under active research for high-temperature applications. While not yet commercialized at scale, such cobalt-rhenium borides are investigated for extreme-environment engineering where traditional superalloys reach their thermal limits, particularly in aerospace and energy sectors where superior high-temperature strength and oxidation resistance are critical.
