| 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. |
