· JVASP-35086· TaTi2N3

TaTi2N3 is a ternary nitride ceramic compound combining tantalum, titanium, and nitrogen, belonging to the family of refractory metal nitrides. This material is primarily investigated in research and advanced materials development for applications requiring exceptional hardness, thermal stability, and wear resistance at elevated temperatures. While not yet widely deployed in mainstream industrial production, tantalum-titanium nitride systems show promise as coatings and composite reinforcements where conventional nitrides reach their performance limits.

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.
