· JVASP-33147· C5N4

C5N4 is a carbon nitride ceramic compound, a hard interstitial material composed primarily of carbon and nitrogen atoms in a stoichiometric ratio. This class of material is primarily investigated in research contexts as a potential superhard ceramic with applications demanding extreme hardness and thermal stability, positioning it as an alternative to traditional abrasives and cutting materials. Carbon nitrides represent an emerging family of materials explored for next-generation wear-resistant coatings, cutting tools, and semiconductor applications where conventional ceramics may fall short.

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.
