MMC’s high specific surface area Mn3O4 product is called MM12, due to the specified minimum value of 12.0 m2/g surface area.
The Mn3O4 is manufactured from high purity electrolytic manganese metal as starting material, resulting in a selenium-free product, suitable for production of all grades of soft ferrites.
Thermogravimetric analysis confirms the high Mn3O4 content (88-93%)
