ceramic

· JVASP-51348· NaH2N

NaH2N (sodium amidide) is an ionic ceramic compound belonging to the metal amide family, characterized by strong ionic bonding between sodium cations and amide anions. While primarily a research material rather than a commodity engineering ceramic, it is investigated for solid-state hydrogen storage applications, ionic conductivity studies, and as a precursor in synthesis of advanced materials—particularly in contexts where reversible hydrogen uptake and strong reducing properties are desired.
