Self-propagating high-temperature synthesis of oxide bronzes with regulated composition and properties

Abstract

Abstract The work is devoted to the preparation of oxide tungsten bronzes of various compositions and various structures by the SHS method. The work is aimed at the realization of the ability to control the composition, structure and properties of SHS products. Brightness pyrometry technique was used for the experimental evaluation of the temperature in the combustion wave. The values of the electrical conductivity of the obtained samples of oxide tungsten bronzes with constant current: for K0.25WO3 — 0,029 S/cm; K0.50WO3 — 0,046 S/cm. Carbon paste electrode was produced and tested based on an oxide bronze K0.50WO3.
