Abstract

A perspective method of small particles reception is the electrical explosion of conductors. As against known methods of evaporation condensation, electrical explosion is characterized by strong nonequilibrium of electrical energy transfer processes in metal dissociation during energy transfer. The process nonequilibrium causes simultaneous coexistence of substances in various conditions: liquid, vaporized, plasma and other. The products of electrical explosion are dependent on the electrical and magnetic field conditions. The properties of received powders strongly depend on the electrical parameters of reception
