SIMULATION OF THE SYNTHESIS OF COMPOSITE PARTICLES OF THE CORE–SHELL TYPE BASED ON CO-OXIDATION OF TITANIUM AND SILICON TETRACHLORIDES IN A PLASMACHEMICAL REACTOR UNDER CONDITIONS OF AGGLOMERATION OF BOTH COMPONENTS

Simulation of one-stage synthesis of composite nanoparticles of titanium dioxide and silicon dioxide in the working zone of a plasmachemical reactor by the chloride method based on the joint oxidation of titanium and silicon tetrachlorides was carried out. The developed synthesis model takes into account the possibility of aggregation not only of titanium dioxide particles that form the cores of composite particles, but also of silicon dioxide particles that do not participate in the formation of the shell. Comparison of the results of calculations by diff erent models is carried out: the size of the cores, the thickness of the shell, and the number of particles of various types.
