چکیده
NdFeB magnets are the most widely used rare earth permanent magnet materials at present. The increasing number of waste and their high content motivate a search for technologies to allow cost-effective environmental-friendly recycling. In this study, removal oxide inclusions from by supergravity technology was investigated separating conditions were optimized maximum removal. Under G = 800 t 15min, total oxygen sample decreased 410 ppm 28 ppm, with efficiency 96.8%. theoretical time remove different sizes calculated Stokes' law, experimental phenomena in good agreement ones. has been demonstrated highly efficient removing A design an industrial reactor presented pave way future commercial processing utilization magnets.

MAGNETIC VISCOSITY IN NdFeB MAGNETS
The relaxation of the magnetization is calculated for isotropic and anisotropic magnets. For NdFeB magnets, the dependence of Sv on texture, above room temperature, is roughly consistent with the model, while the NdDyFeB magnets show no dependence upon texture.
متن کاملExchange-coupled nanoscale SmCo/NdFeB hybrid magnets
Nanoscale hybrid magnets containing SmCo5 and Nd2Fe14B hard magnetic phases have been produced via a novel ‘‘in-one-pot’’ processing route. The grain size of the processed bulk composite materials is controlled below 20 nm. The refinement of the nanoscale morphology leads to effective inter-phase exchange coupling that results in single-phase like magnetic properties. Energy product of 14 MGOe ...

متن کاملThe Pulse-Thermal Processing of ndFeB-Based nanocomposite Magnets
Pulse-thermal processing (PTP) based on high-density plasma arc lamp technology has been utilized to crystallize melt-spun NdFeB-based amorphous ribbons to form magnetic nanocomposites consisting of Nd 2 Fe 14 B and α-Fe phases. After applying suitable pulses, the NdFeB-based ribbons were developed with hard magnetic properties. The highest coercivity can be obtained for ribbons with a thicknes...
متن کاملExtraction and separation of neodymium and dysprosium from used NdFeB magnets: an application of ionic liquids in solvent extraction towards the recycling of magnets
A procedure for the efficient extraction and separation of rare earths and other valuable elements from used NdFeB permanent magnets is presented. In a first step, an iron free leachate is prepared from an used magnet using nitric acid. Cobalt is separated through a liquid–liquid extraction in aqueous nitrate media using as organic phase the ionic liquid trihexyl(tetradecyl)phosphonium nitrate ...
