Hafnium hexaboride (HfB₆) is a refractory ceramic compound combining hafnium metal with boron in a hexaboride crystal structure, belonging to the family of transition metal hexaborides. This material is primarily of research and emerging industrial interest for ultra-high-temperature applications where exceptional thermal stability and hardness are required, particularly in aerospace and advanced thermal protection systems where conventional ceramics reach their performance limits.
