摘要： PROBLEM TO BE SOLVED: To provide an iron nitride material which has a high content of iron nitride particles containing α''FeNas a major ingredient, and to provide a method for manufacturing the same.SOLUTION: Granulated powders having an average particle diameter of 1 μm or more are formed by mixing raw powders made of iron nitride particles which contain α''FeNas a major ingredient and have a minor axis average length of 100 nm or less, and a binder. After a molding die is filled with the granulated powders, a molded body (iron nitride material) is formed by pressure molding. The pressure molding is carried out while performing exhaust of the molding die to be 0.9 atmospheres or less, in a heated state at a temperature of ±20°C of a decomposition temperature of the binder and an applied state of a magnetic field equal to or larger than 2T. By applying a strong magnetic field in the presence of the binder which has melted by heating, transfer and rotation of iron nitride particles become easy and crystal orientation can be oriented in a specific direction. When removing the binder by heating and exhausting, a filling rate of the iron nitride particles can be increased. According to the manufacturing method, iron nitride material having a high content of the iron nitride particles and an oriented texture can be obtained, and the iron nitride material excels in magnetic properties.
