· JVASP-54353· RuN2

RuN2 is a ceramic nitride compound based on ruthenium, belonging to the family of transition metal nitrides. This material is primarily of research interest rather than established industrial production, with potential applications in extreme-environment and high-performance applications where conventional ceramics or metals reach their limits. The nitride class offers the possibility of combining metallic properties (electrical conductivity, thermal conductivity) with ceramic hardness and oxidation resistance, making ruthenium nitride candidates for next-generation protective coatings, hard cutting tools, and high-temperature structural applications in aerospace and energy sectors.
