Modeling of the synthesis of ‘core-shell’ composite particles based on segregated oxidation of titanium and silicon tetrachlorides in flow-type plasmachemical reactor

Abstract

Abstract The simulation of single-stage synthesis of composite titania-silica nanoparticles in the working zone of flow-type plasmachemical reactor has been performed based on segregated oxidation of titanium and silicon tetrachlorides, with each precursor being preliminarily mixed with air oxygen by means of bubbling. Within the framework of the developed model of the synthesis, the data regarding core size of composite particles, their shell thickness as well as ratio of particles with and without shell have been extracted.
