摘要 |
Ferrite having a uniform degree of oxidation is produced at a higher rate of ferrite forming reaction by pelletizing a mixture of iron oxide and ferromanganese powders and calcining the mixture at a temperature of 900 DEG C. or higher. Zinc oxide, magnesium oxide and/or nickel oxide may be further added to the mixture, as required.
