· 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.
