· Re2 N4

Re₂N₄ is a transition metal nitride compound in the rhenium-nitrogen system, representing an experimental high-hardness ceramic material under investigation for extreme-environment applications. This material belongs to the family of refractory nitrides and is primarily of research interest rather than established production use, with potential applications in wear-resistant coatings, high-temperature structural components, and cutting tool materials where rhenium's exceptional hardness and thermal stability can be leveraged. Engineers would consider Re₂N₄ as a candidate material for next-generation applications requiring superior hardness, oxidation resistance, and performance at elevated temperatures beyond what conventional nitrides or carbides provide.

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.
