· JVASP-103049· Ta4N3

Ta4N3 is a ceramic compound belonging to the transition metal nitride family, combining tantalum with nitrogen to form a hard, refractory ceramic. This material is primarily explored in research and advanced applications where extreme hardness, thermal stability, and wear resistance are critical, particularly for cutting tools, wear coatings, and high-temperature structural components where conventional ceramics or steels are insufficient.

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.
