Abstract

This work provides a new and feasible way to prepare MgCNi3 under ambient conditions by ball milling (BM) Mg, Ni powder and paraffin or graphite. It has been found that paraffin is partially dissociated during ball milling, which resulted in free carbon and hydrogen incorporated within the Mg-Ni alloy powder in increasing amounts with increasing milling time. X-ray diffraction analysis indicates that milled Mg-Ni powders react with the paraffin, producing a mixture of MgCNi3 and amorphous Mg-Ni alloy. The electrochemical experiment results show that the discharge capacity of mechanical alloyed (MA) Mg-Ni-based composites was 415 mA h/g. © 2004 Elsevier B.V. All rights reserved.
