Abstract
The process of single-stage synthesis of composite nanoparticles of titanium dioxide and silicon dioxide in the working zone of a plasmochemical reactor is modeled with the use of the chloride method based on joint oxidation of titanium and silicon tetrachlorides. The synthesis model takes into account the possibility of aggregation not only of titanium dioxide particles forming composite particle cores, but also of silicon dioxide particles, which do not participate in the formation of particle shells. The results predicted by various models (core size, shell thickness, and number of particles of various types) are compared.
