Abstract


By means of X-ray diffraction, transmission electron microscopy, and electron diffraction, the structures of modifying oxides have been studied in the nanocomposites based on fumed silica and oxides of magnesium, manganese, nickel, or zinc obtained from metal acetates by liquid-phase modifying followed by thermolysis at 600°С. The formation of crystalline oxide phases Zn, Mn, and Ni in the nanocomposites studied has been shown by transmission electron microscopy.
