Cerium nitride is primarily used in advanced materials and electronic applications due to its unique magnetic and conductive properties. It serves as a key component in the development of rare-earth-based semiconductors and is explored for use in spintronic devices, where electron spin is utilized for information processing. Its high thermal stability makes it suitable for refractory coatings in high-temperature environments. Cerium nitride is also investigated in catalysis, particularly in reactions involving nitrogen activation and hydrocarbon conversion. Additionally, it plays a role in the synthesis of specialized ceramics with enhanced hardness and wear resistance, useful in aerospace and defense technologies.
