· Ta2N

Tantalum nitride (Ta2N) is a refractory ceramic compound combining tantalum metal with nitrogen, belonging to the transition metal nitride family. It is primarily investigated for applications requiring extreme hardness and thermal stability, particularly in thin-film coatings and high-performance cutting tools where conventional materials degrade. Ta2N is of significant research interest for diffusion barriers in microelectronics, wear-resistant coatings on industrial tools, and high-temperature structural applications, though it remains less established in mainstream production compared to more common nitrides like TiN or CrN.

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.
