PURPOSE:To obtain an oxide powder or multiple oxide powder for ferrite capable of producing high-performance and inexpensive ferrite magnets. CONSTITUTION:This oxide powder can be obtained by the following process: a solution of a complex of an amino acid and nitrates essentially containing Fe atom and also containing at least one kind selected from among Ba and Sr atom is heated to a temperature between the boiling point of the solvent and 400 deg.C followed by driving into powder. The multiple oxide powder can be obtained by the following process: a solution of a complex of an amino acid and nitrates essentially containing Fe atom and also containing at least two kinds of atoms selected from among Cu, Mn, Ni and Zn atoms is heated to a temperature between the boiling point of the solvent and 400 deg.C followed by drying into powder. |
