Abstract

The results of investigation into the synthesis conditions and basic characteristics of nanoparticles of titanium dioxide and the mixed oxide (TiO2)x(SiO2)1-x from a gaseous mixture of oxygen, hydrogen, and titanium tetrachloride (or a mixture of titanium and silicon tetrachlorides) are reported. The synthesis was initiated by a pulsed electron beam and was a chain process in character. The geometric dimensions of oxide particles were measured and their X-ray diffraction, X-ray fluorescence, and IR spectrometric studies were performed. It was shown that the nonequilibrium character of the synthesis process induced by a pulsed electron beam allowed the temperature threshold for the formation of the crystalline structure of particles to be lowered.
