Abstract

See full text

A ferromagnetic-particle manufacturing apparatus includes: a single mode cavity that resonates with a microwave of a predetermined wavelength; a microwave oscillator electrically connected to the single mode cavity and configured to introduce the microwave of a predetermined wavelength into the single mode cavity; a pipe disposed to pass through an inside of the single mode cavity, the pipe being formed of a dielectric material; a pump configured to introduce, from one end of the pipe, an alkaline reaction liquid containing metal ions of a ferromagnetic metal; an impedance measuring device configured to measure an impedance of the single mode cavity; and a pump-flowrate deciding unit configured to decide, based on a measurement result of the impedance measuring device, a pump flowrate by which the impedance of the single mode cavity becomes a predetermined value or more; wherein the pump is configured to introduce the reaction liquid at the pump flowrate decided by the pump-flowrate deciding unit; and wherein ferromagnetic particles are generated by reacting the reaction liquid.
