Nano iron tetroxide powder was prepared by aerosol ablation method. It has high purity, small particle size, uniform distribution, large surface area, clean surface, no residual impurities, low loose density, easy to disperse, and has a certain degree of magnetism. In addition, under the external magnetic field, it can be directed, the particle size has super-paramagnetism within a certain range, and it can produce heat and other characteristics under the action of an external alternating electromagnetic field. Its chemical properties are stable, and its use is quite extensive. The small granular ferric tetroxide powder prepared by our co***ny maintains the particle size of magnetic particles in the order of nanometers, and the magnetic particles obtained by magnetic performance test are superparamagnetic, and their technical specifications meet and exceed the performance of magnetic nanometer ferric tetroxide at home and abroad. It provides a basis for the application of various magnetic fluids in China.
