| Abstract: | The effect of the addition of nanosize SiO2 and CaCO3 on the power losses of the manganese zinc ferrites has been investigated. The microstructure and grain boundary of the manganese zinc ferrites were observed by AES and SEM. The results show that the power loss of the manganese zinc ferrites can be reduced by doping nanosize SiO2 additive. |

| Keywords: | power ferrite dopant nanosize material grain boundary microstructure power loss |
