· JVASP-50775· Hf2N2O

Hf2N2O is an advanced ceramic compound combining hafnium, nitrogen, and oxygen—a material family that bridges refractory ceramics and transition metal nitrides. While primarily investigated in research settings, hafnium oxynitrides are explored for ultra-high-temperature structural applications and wear-resistant coatings, where their thermal stability and hardness offer potential advantages over conventional alumina or zirconia ceramics in extreme environments.
