The article describes an installation for producing nanopowders by the method of electrical explosion of a wire. The powders are supposed to be used as a basis for magnetorheological fluids. The article describes the functional installation and the model of the power converter. The electric explosion of the wire was carried out at a voltage of 500 V and 1000 V. The experimental data coincide with the results of the study on the model. The pulse duration is ∼ 10 −4 s, and the power is in the range from 1.5 MW to 4 MW. Spherical particles are obtained in the size of 500-5000 n with such parameters of an electric explosion. The surface of the particles was examined on a Tescan VEGA II electron microscope.
