· JVASP-110989· TaVB4

TaVB4 is a refractory metal boride compound combining tantalum, vanadium, and boron, belonging to the family of ultra-high-temperature ceramics and hard materials. This material is primarily of research and developmental interest for extreme-environment applications where conventional superalloys reach their thermal limits, with potential use in aerospace propulsion, cutting tools, and armor systems where exceptional hardness and thermal stability are critical.
