发明名称 FERRITE MATERIAL AND ITS PRODUCTION
摘要 PROBLEM TO BE SOLVED: To provide a ferrite material small in the dimensional change rate on sintering, having excellent magnetic characteristics and used for various electronic parts, and further to provide a method for producing the ferrite material. SOLUTION: This ferrite material is produced by mixing ferrite-forming oxides with a mixture obtained by partially or wholly replacing one or more kinds of the oxides with the powder of one or more metals, adding the obtained mixture to ferrite calcination powder obtained by mixing and calcinating the powder of ferrite raw materials, granulating the mixed powder, molding the granules and subsequently calcining the molded product. Therein, the average particle diameter of the added metal powder is <=15&mu;m, and the particle diameter of the metal powder or its aggregation powder dispersed in a molded product is <=30&mu;m.
