Production of RCo5 and R2Co7 powders by the R/D process

  • 1. Hitachi Magnetics Corp., Edmore, MI

Description

Manufacturing processes based on the Reduction-Diffusion (R/D) process have been developed. A pilot plant with an annual capacity in excess of 35 metric tons is in operation. Both base, SmCo5, and additive, Sm2Co7, powders are produced in a routine manner. The reproducibility of the processes is excellent. Magnets made from mixtures of these powders exhibit outstanding permanent magnet properties. The raw material and process cost reductions associated with the R/D process have led to an 8-fold reduction in the published price of Sm-Co magnet alloy since 1971. The commercial success of this project represents a milestone in the emerging uses of rare earths
