Current Research Situation of High Initial Magnetic Permeability Manganese Zinc Ferrites
As the widely used non-metallic functional ceramic material,the output of high permeability manganese-zinc ferrite accounted for more than 30%of that of soft magnetic ferrites,which was one of the important basic raw materials in the production of the national economy.It was divided into three parts,namely the development process,research and appli-cation at home and abroad of high initial permeability manganese-zinc ferrite material to explain it.Firstly,the development process at home and abroad was elaborated in chronological sequence,and explained it.By comparing the performance of high initial permeability manganese-zinc ferrite materials at home and abroad,it showed that the high initial permeability manganese-zinc ferrite material produced in China was not worse than that of foreign products,indeed the electrical proper-ties of some high permeability manganese-zinc ferrites were better than those the same type of foreign ones.Secondly,the research situation at home and abroad was discussed according to production process,which consisted of the principal com-ponents,trace additives,sintering process and coating process as well as their corresponding functions.Lastly,the applica-tion situation at home and abroad was analyzed by illustrating the application areas,which indicated that the real application would weigh multinomial property
