Influence of Particle Size and Ca Addition on the Magnetic Performance and Microstructure of MnZn Ferrite

In this work, the influence of Ca addition on the power loss of MnZn ferrites was investigated. Mn–Zn ferrites were prepared by conventional oxide ceramic process from calcined powders of different particle sizes in equilibrium sintering atmosphere. It has been found that the optimal amount of Ca addition varies for the Mn–Zn ferrites synthesized by using powders of different particle size.
