| Abstract: | Nanometric sodium hydride (NaH*) possesses a large specific surface area. Its chemical reactivity is in orders of magnitude 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 chemical reactivity. |
