Abstract: The influence of a quenching air jet on physical and chemical properties and morphology of titanium dioxide, silicon dioxide, and TiO$_2$–SiO$_2$ composite particles synthesized by the single-stage chloride method in a flow-type plasma-chemical reactor is studied. The results of the simulations and analysis of the specimens show that the physical and chemical properties of the powder and the morphology of its particles can be controlled. It is demonstrated that the results of mathematical simulations of the synthesis of TiO$_2$ and SiO$_2$ particles agree well with the experimental data obtained in the study.

Keywords: titanium dioxide, silicon dioxide, composite particle, plasma-chemical reactor, one-velocity multicomponent medium, homogeneous and heterogeneous reactions, coagulation.
