摘要：
The preliminary action of a high-gradient electromagnetic field on dry ferrite powder did not change the. optimum sintering temperature of anisotropic magnets and made it possible to significantly reduce the heat treatment time as the result of an increase in heating rate. The resonant texturing method makes it possible to form a fine-grained uniform structure of barium ferrite magnets. Their residual induction increased by 16% and their coercive force by 47% in comparison with specimens produced by "wet" pressing. © 1990 Plenum Publishing Corporation.
