· JVASP-36325· HfN2

HfN₂ is a ceramic nitride compound based on hafnium, belonging to the refractory nitride family known for exceptional hardness and thermal stability. While primarily investigated in research settings, hafnium nitrides are pursued for ultra-high-temperature applications and hard coatings where conventional materials fail, particularly in aerospace and cutting-tool industries seeking alternatives to traditional carbides and nitrides.
