摘要：

The ball milled nanocrystalline Mg72Li28 compound before and after lixiviation in water was investigated by neutron and X-ray scattering. The specific surface area before and after treatment was precisely measured. The crystallographic parameters were extracted by Rietveld refinement. It was found that with energetic ball milling, the solubility limit of magnesium in lithium was slightly increased. By lixiviation. all Lithium was leached. In order to reduce the amount of metal oxides and hydroxides, the conditions of lixiviation have to be optimized. (C) 1999 Elsevier Science S.A. All rights reserved.
