对多晶LiAlH4的机械化处理表明，这种复合铝氢化物在氦气气氛中高能球磨35h时具有良好的稳定性。在长达110h的机械力化学处理过程中，观察到锂铝氢化物分解为Li3AlH6、Al和H-2，这很可能与小瓶材料铁的催化作用有关，铁在机械处理过程中作为污染物引入氢化物中。(C)2000 Elsevier Science B.V.保留所有权利。
Mechanochemical processing of polycrystalline LiAlH4 revealed good stability of this complex aluminohydride during high-energy ball-milling in a helium atmosphere for up to 35 h. The decomposition of lithium aluminohydride into Li3AlH6, Al and H-2 is observed during prolonged mechanochemical treatment for up to 110 h and is most likely associated with the catalytic effect of a vial material, iron, which is introduced into the hydride as a contaminant during mechanical treatment.
