· JVASP-35042· Re2N

Re2N is a refractory ceramic compound composed of rhenium and nitrogen, belonging to the family of transition metal nitrides known for extreme hardness and thermal stability. This material is primarily of research and development interest rather than established commercial production, with potential applications in high-temperature structural components and wear-resistant coatings where conventional ceramics reach their performance limits. Rhenium nitrides are investigated as candidates for ultra-hard tool materials and advanced aerospace applications due to their exceptional hardness and resistance to oxidation at elevated temperatures, though cost and manufacturing challenges currently limit widespread industrial adoption.
