Features of secondary recrystallization in firing of hot-pressed manganese-zinc ferrites

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

The effect of secondary recrystallization and coarsening of the structure in annealing of hot pressed manganese-zinc ferrites may be used for substantially increasing their initial magnetic permeability.

Using type MM2 industrial iron oxide containing impurities, by selection of the appropriate hot pressing and annealing conditions it is possible to obtain ferrite cores with a record value of initial magnetic permeability at the level of 30,000 units.
