MODELING THE SYNTHESIS OF COMPOSITE TITANIAAND SILICA-BASED CORE–SHELL TYPE PARTICLES IN A PLASMACHEMICAL REACTOR

One-stage synthesis of composite titania and silica nanoparticles in the working area of a plasmachemical reactor by a chloride method, which is based on separate oxidation of titanium and silicon tetrachlorides, has been modeled for the fi rst time. The infl uence of a number of parameters of the physicomathematical model on both the general size of the particles and the shell thickness has been investigated. Results of calculations for certain variants of the parameters have been given.
