· Ta3 N3

Ta3N3 is a tantalum nitride ceramic compound belonging to the family of refractory nitrides, which are known for exceptional hardness and thermal stability. While primarily of research interest rather than established commercial production, tantalum nitride materials are investigated for high-temperature structural applications, wear-resistant coatings, and advanced electronic devices where their combination of hardness, chemical inertness, and potential electrical properties offers advantages over conventional oxides and carbides.

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.
