· JVASP-112000· Np2C3

Np₂C₃ is a neptunium carbide ceramic compound belonging to the actinide carbide family, characterized by high density and ceramic properties typical of refractory carbide materials. This material is primarily of research and specialized nuclear fuel cycle interest rather than established commercial production, with potential applications in advanced nuclear materials where chemical stability and thermal properties are critical. Neptunium carbides are studied as alternatives or supplements to more conventional uranium and plutonium-based carbides in nuclear fuel development and materials science research.
