CN104388986A 一种熔盐电解法制备铜镁合金的生产工艺 无效 - 驳回

一种熔盐电解法制备铜镁合金的生产工艺
摘要：
本发明涉及一种熔盐电解法制备铜镁合金的生产工艺，该生产工艺以氧化镁或氯化镁或者碳酸镁为原料，采用纯铜为阴极，石墨为阳极，解质体系由氟化镁或氯化镁和碱金属或碱土金属的氯化物和氟化物组合而成，在温度为750～950℃时，MgO或MgCl2或者Mg2CO3发生电离，Mg2+在铜阴极表面析出，被还原为Mg，Mg与Cu合金化形成Cu-Mg，直接生成铜镁合金。本发明与目前的熔炼对掺法相比，具有节能，简化流程，合金无偏析，无金属的二次烧损等优点。
摘要（英）：

The invention relates to a production process for preparing copper-magnesium alloy by virtue of a molten salt electrolysis method. According to the production process, magnesium oxide or magnesium chloride or magnesium carbonate is taken as a raw material, pure copper is taken as a negative electrode, graphite is taken as a positive electrode, and an electrolysis system is formed by combining magnesium fluoride or magnesium chloride with chlorides and fluorides of alkali metals or alkaline-earth metals; MgO or MgCl2 or Mg2CO3 ionizes at 750-950 DEG C, Mg<2+> is separated from a copper negative electrode and is reduced into Mg, and Mg and Cu are alloyed to directly generate Cu-Mg, namely the copper-magnesium alloy. Compared with an existing smelting-doping method, the production process has the advantages that the energy is saved, the technological process is simplified, alloy segregation and secondary metal burning are avoided, and the like.
