HfTaN3
semiconductor· HfTaN3
HfTaN3 is a refractory ceramic compound combining hafnium, tantalum, and nitrogen, belonging to the family of transition metal nitrides and carbides. This material is primarily of research interest for extreme-environment applications where thermal stability and hardness are critical; it represents the broader class of high-entropy and multi-element nitride ceramics being investigated as alternatives to traditional refractory coatings and structural ceramics in aerospace and nuclear contexts.
