On Obtaining of Ultrafine Metal Powders at Electric Explosion of Conductors in Liquid Part I. Peculiarities of Explosion of Conductors in Liquid

The features of electric explosion and dispersion in a liquid of metallic conductors with their thermodynamic and electric parameters differing over a wide range were investigated. The experimental data analysis allowed selecting three pairs of metals being the closest in the obtained parameters of the explosion. It is obvious that the size of the obtained particles depends on the density of the energy injected into the conductor mass unit by the moment of explosion. A reverse dependence between the energy of the arc stage of the explosion and the size of the particles is found. The distribution of the obtained particles by size is more homogeneous than at the explosion of conductors in gases.
