· JVASP-100304· ScTaN2

ScTaN2 is a transition metal nitride ceramic compound combining scandium and tantalum, belonging to the class of refractory nitride ceramics. This material is primarily of research and emerging applications interest, investigated for high-temperature structural applications, wear-resistant coatings, and advanced ceramic composites where extreme hardness and thermal stability are required. Its appeal lies in the potential to combine scandium's lightweight characteristics with tantalum's exceptional refractory properties, offering possibilities for next-generation aerospace and tooling applications where conventional nitride ceramics reach performance limits.
