Effect of the Formation Method of ZnO–In2O3 Composites on Their Structural Characteristics and Conductivity

Composites based on indium oxide containing different amounts of zinc oxide are synthesized by hydrothermal and impregnation methods. The phase composition, structure, and specific surface of the obtained composites are studied by various physicochemical methods. The electrophysical properties of composites synthesized by different methods are compared. It is shown that the method of formation has a significant effect on the structural characteristics of the composites, which in turn leads to the implementation of various conduction mechanisms.
