· HfN

Hafnium nitride (HfN) is a refractory ceramic compound belonging to the transition metal nitride family, characterized by extremely high melting point and thermal stability. It is primarily investigated for extreme-environment applications in aerospace, nuclear, and high-temperature industrial settings where conventional ceramics and metals reach their limits. HfN is notably harder and more chemically resistant than many competing refractory materials, making it a candidate for thermal protection systems, cutting tools, and reactor components, though industrial adoption remains limited compared to more established carbides and established nitrides.
