PURPOSE:To provide magnetic powder for bonded magnet, which possesses high magnetic characteristic and a high cost performance in combination, and a method of manufacturing the magnetic powder by a method wherein the magnetic powder is realized in such a process that a grinding process is not required. CONSTITUTION:One kind or more than two kinds of metal salts made to dissolve in a solution are mixed with a precipitating medium made to dissolve or dispersed in the solution and precipitated fine particles are made to produce in the solution as a precursor. After that, magnetic powder is produced by a method of reducing fine particles. Thereby, magnetic powder for bonded magnet, which is an aggregate consisting of alloy fine particles having a mean particle diameter of 0.001 to 1.0mum and is made of aggregated particles having a mean particle diameter of 1.0 to 500mum, can be obtained. Accordingly, it becomes possible to realize the magnetic powder by a single process, which does not require grinding process unlike a conventional process, and magnetic powder for bonded magnet, which is superior in cost performance, can be obtained. |
