METHOD OF BARIUM FERRITE POWDER

摘要

To be able to produce the barium ferrite at a lower temperature, the compound of the particle powder of magnetite in super-micro powder phase and of the barium is adjusted to the a mol ratio, 3.3 : 1 - 3.9 : 1, (FeO : Ba) to be wet-mixed, then under the atmospheric pressure, within the temperature of 600~800 degree C this compound is subjected to the heat treatment as to be completed to the micro powder.
