Research of electro-explosive iron powder using the hydrolytic adsorption method

Abstract

This work is aimed at solving the urgent problem associated with the diagnostic and forecasting of functional characteristics of finely dispersed materials. It considers the effect of primary acid-base center characteristics on the wetting process. The research of hydrolytic adsorption is carried out using the nano-dimensional iron powders. The powders were obtained by applying the method of electric explosion of conductors, after that they were passivated under different conditions. The identification of composition and structure of the passivating oxide film was carried out applying the method of transmission electron microscopy and X-ray diffraction analysis. The paper also describes the inhibition mechanism of hydrolytic adsorption on ferrioxide compounds with different composition and structure. The inhibition mechanism explains the hydrophilic / hydrophobic behavior of oxide compounds. The material of this article can be useful for its implementation in industrial, research and school laboratories.
