Combustion in the Cu(NO3)2−Al(NO3)3−H2O–Polyvinyl Alcohol System: Synthesis of CuO/Al2O3

Аннотация

This paper presents the results of a study of combustion processes in the Cu(NO₃)₂-Al(NO₃)₃-H₂O-polyvinyl alcohol (PVA) system, the composition and characteristics of the phases formed, the influence of heat-treatment conditions on the phase formation and particle sizes of powders. It is shown that the combustion of organic-inorganic mixtures can be used to obtain CuO/Al₂O₃ catalysts or precursors of Cu/Al₂O₃ catalysts and copper-matrix composites for electrical contacts.
