Abstract
Single-stage synthesis of composite nanoparticles of titanium dioxide and silicon dioxide in the test section of a plasma-chemical reactor with the use of a chloride method based on simultaneous oxidation of titanium and silicon tetrachlorides with preliminary mixing of the reactants by means of bubbling is simulated. Within the framework of the model developed in the study, data on the size of the composite particle core, particle shell thickness, and number of particles with and without the shell are obtained.
