Process for preparing nanocrystalline and X-rays-amorphous metal powder |
摘要 |
Prepn. of amorphous or nanocrystalline gp. IB to VIIIB metal powder (I) comprises reacting the corresp. metal halide with an alkali(ne earth metal) hydride, with continuous milling. Pref. MgH2 is used, which is produced by hydrogenating Mg with addn. of MgH2 or finely-divided, highly reactive Mg as catalyst in the first hydrogenation. Gp. IB, IVB and VIIIB metal halides are used. |
