The production of rare-earth-sintered magnets by a low-cost powder technique

This paper describes a simple system which may be constructed in the laboratory to produce rare-earth iron–boron permanent magnets. Unlike conventional preparation of sintered magnets in laboratory, the technique described does not require a glove box. Sintered Nd-based magnets have been successfully produced using this new technique and the hydrogen decrepitation (HD) process. The technique proved to be very useful for studying magnets on a laboratory scale.
