| Abstract Scope |
Alloys of transition metals and rare earth elements are widely used as magnet materials in many industries including the clean energy sector. Currently, these magnets are prepared by a mixing-cum-melting technique. Efforts are currently underway to develop innovative ways to cut down the overall manufacturing costs of these magnets. Two of these efforts include preparation of these magnets by an electrochemical technique directly from their mixed oxide precursors and recycling of spent magnets. In the present research, an attempt was made to fabricate the neodymium iron (NdFe) master alloy directly from the mixed oxide precursors (Nd2O3 and Fe2O3 respectively) by cathodic polarization of the sintered precursors in a pool of molten calcium chloride at a temperature of 800oC. The presentation will discuss detailed experimental approaches pertaining to the fabrication of the oxide precursors and their subsequent electrochemical polarization to the alloy phase. |
