metal

· JVASP-35663· Lu3AlN

Lu3AlN is a ternary nitride ceramic compound combining lutetium, aluminum, and nitrogen, representing an advanced intermetallic/ceramic hybrid material. This is a research-phase material primarily investigated for high-temperature structural and electronic applications where the combination of refractory properties and potential semiconducting behavior is advantageous. Lu3AlN belongs to the broader family of rare-earth aluminum nitrides, which are explored as alternatives to conventional carbides and oxides in extreme environments where thermal stability, hardness, and chemical inertness are critical.
