    摘要: A method of making a polycrystalline Mn containing ferrite body composed of crystallites which have the (111)-crystallographic planes thereof oriented substantially parallel with each other. The method involves providing a manganese compound, forming a body of a mixture made up of the manganese compound and other ferrite constituents, and heating the body made of the mixture into a polycrystalline Mn containing ferrite body of a spinel structure, wherein the manganese compound is in the form of thin platelets which have substantially parallel major surfaces oriented substantially in one direction in the body of the mixture. The ferrite body made thereby is a dense polycrystalline ferrite body having improved resistance to crumbling, improved wear characteristics and suitable physical properties for e.g. magnetic heads.
