Abstract

Effect of citric acid (φ = 0.5–1.3) and glycine (φ = 0.5; 0.7–0.9) ratio on the rate of combustion reactions, phase composition, and particle size of CuO<subscript>x</subscript> powder obtained from copper nitrate solution under conditions of open and closed reactors has been considered. Modeling of combustion reactions for the synthesis of CuO<subscript>x</subscript> has shown that calculations of T<subscript>max</subscript> by equation derived for synthesis in combustion reactions are possible also for thermolysis or pyrolysis reactions. Formation, morphology, and dispersity of samples after completion of combustion reactions and thermal treatment at 500°C have been studied by X-ray diffraction and electron microscopy. The characteristics of combustion profiles display transition from bulk combustion mode to self-propagating high-temperature synthesis and further to thermolysis of xerogels when citric acid content increases. It has been found that retardation of redox reaction rate does not decrease CuO loss due to removal of copper within organic volatile components. [ABSTRACT FROM AUTHOR]
