The present review is concerned with the development of the power ferrite with high performance and low cost, which is especially manufactured by use of the spray roasting of Fe-Mn binary system. Electro-magnetic properties of ferrite are influenced by chemical composition and microstructure and also being very sensitive for stress induced in the grain and bulk. Therefore, to obtain the ferrite having high performance by the conventional solid phase reaction process, it is very important to use raw material powder with high purity and good dispersion itself. The highly homogeneous dispersion of Fe and Mn ions which are consist of the main composition of power ferrite, was successfully carried out by our new process which is characterized by the spray roasting the mixed solution of both Fe and Mn chloride, purified in advance. We finally established the whole process from raw materials to sintering process for the production of ferrite with higher performance and lower cost.
