Characteristics of composite titanium dioxide and silicon dioxide nanoparticles with a structure of the core–shell type, synthesized by the chloride method in a continuous plasmachemical reactor with supply of reagents by different schemes, were investigated. For the composite nanoparticles obtained by these schemes, data on the size of the core of the particles, the thickness of their shell, and the ratio between the number of the particles covered with a shell and the number of the particles with no shell in a unit volume of the reactor have been obtained.
