· JVASP-36234· TaN2

Tantalum nitride (TaN₂) is a ceramic compound belonging to the transition metal nitride family, characterized by high hardness and thermal stability. It is primarily investigated for wear-resistant coatings, thin-film applications in microelectronics, and high-temperature structural components, where its hardness and chemical inertness make it attractive as an alternative to traditional hard coatings like TiN or CrN. As a research material, TaN₂ shows particular promise in applications requiring resistance to oxidation and mechanical wear in aggressive thermal or chemical environments.
