Abstract Low power MnZn power ferrites were prepared using traditional oxide ceramic methods. The effects of
TiO2 doping on the microstructure, saturation magnetic induction, initial magnetic permeability, and power loss of
power ferrites were studied. The results show that adding an appropriate amount of TiO2 can improve grain uniformity,
increase saturation magnetic induction strength, initial magnetic permeability, and reduce losses, especially at
low temperatures. However, adding too much TiO2 can cause abnormal grain growth, decrease saturation magnetic
induction strength, and worsen high temperature losses. When the TiO2 content is 0.25%, the ferrite sintered samples
have uniform grain size, maximum saturation magnetic induction strength, and low loss.
