Abstract

The characteristics of nanopowders obtained by the method of electrical explosion of molybdenum wires were investigated: the particle diameters, the particle size distributions. Controlling factors were electrical parameters and composition of surrounding gases in the explosive chamber. The molybdenum powders having maximum dispersiveness were produced using nitrogen as surroundings during explosion. The thermal activity of the prepared molybdenum powders at the heating in air has been studied.

Keywords
