摘要: 目前,国外普遍采用高温熔炼法制备Mg2Cu,这种方法的优点是工艺比较简单,缺点是产物表面性能较差,吸、放氢速度较慢,且使用前必须经过粉碎。

Abstract: A new method for the synthesis of Mg2Cu is presented. The main feature of the method is using a suitable nonaqueous solution of cupric salt, such as CuCl2 in predried methylcyanide, to react with magnesium filings in an atmosphere of argon. The replaced copper is deposited on the surface of Mg. After heating the alloy at 500-580℃ under an atmosphere of argon for homogeneity, Mg2Cu is obtained as a dark grey powder. The properties of this chemically synthetic intermetallic compound are essentially inden-tical with those reported in the literature.
