Abstract
Nanocomposites based on AgI and Al2O3 have been obtained using the techniques of chemical condensation, mechanical treatment, and crystallization. The size of the particles is estimated using the scanning-electron-microscopy technique. After mechanical treatment and crystallization, the AgI composite is composed of nanoparticles of silver iodide, which are localized in the shells of nanocrystalline aluminum oxide. The size of the particles and the thickness of the shells are determined. The results are discussed based on considerations that describe the microscopic mechanisms responsible for the formation of silver iodide nanocrystals in the process of mechanical treatment and crystallization. It is shown that the shape and structure of the composite nanoparticles change depending on the method and conditions of their production.
