· LaN

Lanthanum nitride (LaN) is a ceramic compound belonging to the rare-earth nitride family, characterized by its high hardness and refractory properties. It is primarily of research and development interest for advanced applications requiring thermal stability and chemical resistance at elevated temperatures. LaN and related rare-earth nitrides are being investigated for use in cutting tool coatings, wear-resistant components, and high-temperature structural applications where conventional ceramics may be inadequate.
