· JVASP-78398· RuN

Ruthenium nitride (RuN) is a transition metal nitride ceramic combining ruthenium with nitrogen, belonging to the broader family of refractory ceramic compounds known for exceptional hardness and thermal stability. This material is primarily investigated in research and emerging industrial applications where its high density and stiffness support demanding mechanical and thermal environments. RuN is valued in specialized coatings, hard surface applications, and advanced catalyst systems, offering potential advantages over traditional carbides in corrosion resistance and chemical stability, though it remains less commercially established than tungsten carbide or titanium nitride for conventional cutting tools.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
