Study of reaction mechanism in solution combustion synthesis of transition metals

Abstract

In this paper, we investigate the reaction mechanism followed during the solution combustion synthesis of transition metals (Cu, Ni and Co) and their alloys. Metal nitrates were mixed with a choice of fuel (glycine, and urea) and mixed in deionized water to get a homogeneous mixture of solution with uniform properties. The solution thus obtained is heated to initiate the highly exothermic combustion reaction resulting in the synthesis of metals/metal-oxides. TGA-DTA analysis of the reactants (metal-nitrates, fuel, and cellulose) along with the XRD of the final products obtained helped in deducing the reaction mechanism.
