Abstract
Nanocrystalline (8–10 nm) solid solutions on the basis of indium oxide in the systems In2O3–ZrO2 and In2O3–HfO2 are synthesized by hydroxide coprecipitation. It is established that the use of polyvinyl alcohol decreases the degree of agglomeration of precipitates and increases the dispersity of the synthesized powders. The optimal conditions for the consolidation of powders on the basis of In2O3 are selected. It is shown that In2O3 doping with zirconium and hafnium dioxides significantly increases the electrical conductivity of solid solutions compared to pure indium oxide. The influence of temperature and oxygen partial pressure on the conductivity of solid solutions on the basis of In2O3 was investigated.
