ceramic

· JVASP-28374· CN2

CN2 is a ceramic compound from the carbon-nitride family, representing a class of materials engineered to combine carbon and nitrogen in crystalline or semi-crystalline forms. This material is primarily of research and developmental interest, with investigations focused on applications requiring high stiffness, thermal stability, and chemical inertness. CN2 and related carbon-nitride ceramics show promise in structural applications, protective coatings, and high-performance composite reinforcement where superior hardness and modulus are critical design drivers.
