摘要
Nanometric sodium hydride (NaH) possesses a large specific surfacr area. Its chemical reactivity is in orders of inagnitude higher than that of the conmercial one. After heat treatment at 2ll℃, the specific surface area of NaH becomes smaller whereas its chemical reactivity is even higher. This fact indicates that the specific surface area of NaH particles is an important but not the only factor for its high reactivity. NaH treated at (400℃, 6h) still retains a specific surface area of 30m2 g-1 and gives fairly high chenncal reactivity.
