The features of using standard physicochemical methods of analysis for determining the basic characteristics of metal nanopowders are discussed. The methods for the analysis of the shape and size of particles, the value of the specific surface area, the particle size distributions, and parameters of chemical activity of metal nanopowders are considered. The combination of these diagnostic characteristics makes it possible to predict the technical properties of metal nanopowders and evaluate their qualities for use in technology. The experimental results of diagnostics of aluminum and tungsten nanopowders produced by the electric explosion of wires are presented. |
