Effects of Anneal Temperature on the Properties of High Permeability MnZn Ferrite

High initial permeability MnZn soft magnetic materials were fabricated by Oxide ceramic technology, and get microstructure of high initial permeability MnZn by Scanning Electron Microscope(SEM). Examined the effect of anneal temperature on the microstructure and magnetic properties of MnZn ferrite, And get that the anneal temperature of 960℃ is the best one for high initial permeability MnZn soft magnetic material, and get the initial permeability is about 9 500.
