The method of production to prepare rare-earth hydrogen-stored alloys intended to be used for producing Ni-MH batteries is stated in brief. Multi-element rare-earth hydrogen-stored alloy ingots have been obtaineal by induction melting method of using ceramic crucible and water-cooling crucible, respectively. It is indicated that the concentration of impurity carried into the melt can be limited within some hundreds of ppm. By using a suitable water-cooling ceramic crucible, we can obtain the uncontaminated alloy ingots with homogenous and accurate composition. The process characteristics. of induction melting method with cold crucible and the result analysis of hydrogen stored alloy ingots obtained are introduced as well.
