· JVASP-85272· C3N4

C3N4 (carbon nitride) is a hard ceramic compound composed of carbon and nitrogen atoms, belonging to the family of lightweight high-strength ceramics. While primarily investigated in research and development rather than widespread industrial production, it is of growing interest for applications demanding exceptional hardness, thermal stability, and chemical resistance—particularly in scenarios where traditional ceramics or diamond alternatives are cost-prohibitive or functionally limiting. Its layered crystal structure and potential for exfoliation make it especially promising for next-generation composite reinforcement, tribological coatings, and semiconductor applications where both mechanical performance and functional properties are critical.

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.
